+ *
+ * The Marvell EBU SoCs have a configurable physical address space:
+ * the physical address at which certain devices (PCIe, NOR, NAND,
+ * etc.) sit can be configured. The configuration takes place through
+ * two sets of registers:
+ *
+ * - One to configure the access of the CPU to the devices. Depending
+ * on the families, there are between 8 and 20 configurable windows,
+ * each can be use to create a physical memory window that maps to a
+ * specific device. Devices are identified by a tuple (target,
+ * attribute).
+ *
+ * - One to configure the access to the CPU to the SDRAM. There are
+ * either 2 (for Dove) or 4 (for other families) windows to map the
+ * SDRAM into the physical address space.
+ *
+ * This driver:
+ *
+ * - Reads out the SDRAM address decoding windows at initialization
+ * time, and fills the mbus_dram_info structure with these
+ * informations. The exported function mv_mbus_dram_info() allow
+ * device drivers to get those informations related to the SDRAM
+ * address decoding windows. This is because devices also have their
+ * own windows (configured through registers that are part of each
+ * device register space), and therefore the drivers for Marvell
+ * devices have to configure those device -> SDRAM windows to ensure
+ * that DMA works properly.
+ *
+ * - Provides an API for platform code or device drivers to
+ * dynamically add or remove address decoding windows for the CPU ->
+ * device accesses. This API is mvebu_mbus_add_window_by_id(),
+ * mvebu_mbus_add_window_remap_by_id() and
+ * mvebu_mbus_del_window().

+
+Required properties:
+- #address-cells, #size-cells : Must be present if the device has sub-nodes

+- compatible : Should be the manufacturer and the name of the chip. Bear in

+
+Optional properties:
+ - memory-map : Address and size of the flash, if memory mapped. This may
+ apply to Intel chipsets, which tend to memory-map flash.
+
+Example:
+
+ flash: m25p80@0 {
+ #address-cells = <1>;

+Soft SPI
+
+The soft SPI bus implementation allows the use of GPIO pins to simulate a
+SPI bus. No SPI host is required for this to work. The down-side is that the
+performance will typically be much lower than a real SPI bus.
+
+The soft SPI node requires the following properties:
+
+compatible: "u-boot,soft-spi"
+soft_spi_cs: GPIO number to use for SPI chip select (output)
+soft_spi_sclk: GPIO number to use for SPI clock (output)
+soft_spi_mosi: GPIO number to use for SPI MOSI line (output)
+soft_spi_miso GPIO number to use for SPI MISO line (input)
+spi-delay-us: Number of microseconds of delay between each CS transition
+
+The GPIOs should be specified as required by the GPIO controller referenced.
+The first cell holds the phandle of the controller and the second cell
+typically holds the GPIO number.
+
+
+Example:
+
+ soft-spi {
+ compatible = "u-boot,soft-spi";
+ cs-gpio = <&gpio 235 0>; /* Y43 */
+ sclk-gpio = <&gpio 225 0>; /* Y31 */
+ mosi-gpio = <&gpio 227 0>; /* Y33 */
+ miso-gpio = <&gpio 224 0>; /* Y30 */
+ spi-delay-us = <1>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cs@0 {
+ };

+How to port a SPI driver to driver model
+========================================
+
+Here is a rough step-by-step guide. It is based around converting the
+exynos SPI driver to driver model (DM) and the example code is based
+around U-Boot v2014.10-rc2 (commit be9f643).
+
+It is quite long since it includes actual code examples.
+
+Before driver model, SPI drivers have their own private structure which
+contains 'struct spi_slave'. With driver model, 'struct spi_slave' still
+exists, but now it is 'per-child data' for the SPI bus. Each child of the
+SPI bus is a SPI slave. The information that was stored in the
+driver-specific slave structure can now be port in private data for the
+SPI bus.
+
+For example, struct tegra_spi_slave looks like this:
+
+struct tegra_spi_slave {
+ struct spi_slave slave;
+ struct tegra_spi_ctrl *ctrl;
+};
+
+In this case 'slave' will be in per-child data, and 'ctrl' will be in the
+SPI's buses private data.
+
+
+0. How long does this take?
+
+You should be able to complete this within 2 hours, including testing but
+excluding preparing the patches. The API is basically the same as before
+with only minor changes:
+
+- methods to set speed and mode are separated out
+- cs_info is used to get information on a chip select
+
+
+1. Enable driver mode for SPI and SPI flash
+
+Add these to your board config:
+
+#define CONFIG_DM_SPI
+#define CONFIG_DM_SPI_FLASH
+
+
+2. Add the skeleton
+
+Put this code at the bottom of your existing driver file:
+
+struct spi_slave *spi_setup_slave(unsigned int busnum, unsigned int cs,
+ unsigned int max_hz, unsigned int mode)
+{
+ return NULL;
+}
+
+struct spi_slave *spi_setup_slave_fdt(const void *blob, int slave_node,
+ int spi_node)
+{
+ return NULL;
+}
+
+static int exynos_spi_ofdata_to_platdata(struct udevice *dev)
+{
+ return -ENODEV;
+}
+
+static int exynos_spi_probe(struct udevice *dev)
+{
+ return -ENODEV;
+}
+
+static int exynos_spi_remove(struct udevice *dev)
+{
+ return -ENODEV;
+}
+
+static int exynos_spi_claim_bus(struct udevice *dev)
+{
+
+ return -ENODEV;
+}
+
+static int exynos_spi_release_bus(struct udevice *dev)
+{
+
+ return -ENODEV;
+}
+
+static int exynos_spi_xfer(struct udevice *dev, unsigned int bitlen,
+ const void *dout, void *din, unsigned long flags)
+{
+
+ return -ENODEV;
+}
+
+static int exynos_spi_set_speed(struct udevice *dev, uint speed)
+{
+ return -ENODEV;
+}
+
+static int exynos_spi_set_mode(struct udevice *dev, uint mode)
+{
+ return -ENODEV;
+}
+
+static int exynos_cs_info(struct udevice *bus, uint cs,
+ struct spi_cs_info *info)
+{
+ return -ENODEV;
+}
+
+static const struct dm_spi_ops exynos_spi_ops = {
+ .claim_bus = exynos_spi_claim_bus,
+ .release_bus = exynos_spi_release_bus,
+ .xfer = exynos_spi_xfer,
+ .set_speed = exynos_spi_set_speed,
+ .set_mode = exynos_spi_set_mode,
+ .cs_info = exynos_cs_info,
+};
+
+static const struct udevice_id exynos_spi_ids[] = {
+ { .compatible = "samsung,exynos-spi" },
+ { }
+};
+
+U_BOOT_DRIVER(exynos_spi) = {
+ .name = "exynos_spi",
+ .id = UCLASS_SPI,
+ .of_match = exynos_spi_ids,
+ .ops = &exynos_spi_ops,
+ .ofdata_to_platdata = exynos_spi_ofdata_to_platdata,
+ .probe = exynos_spi_probe,
+ .remove = exynos_spi_remove,
+};
+
+
+3. Replace 'exynos' in the above code with your driver name
+
+
+4. #ifdef out all of the code in your driver except for the above
+
+This will allow you to get it building, which means you can work
+incrementally. Since all the methods return an error initially, there is
+less chance that you will accidentally leave something in.
+
+Also, even though your conversion is basically a rewrite, it might help
+reviewers if you leave functions in the same place in the file,
+particularly for large drivers.
+
+
+5. Add some includes
+
+Add these includes to your driver:
+
+#include <dm.h>
+#include <errno.h>
+
+
+6. Build
+
+At this point you should be able to build U-Boot for your board with the
+empty SPI driver. You still have empty methods in your driver, but we will
+write these one by one.
+
+If you have spi_init() functions or the like that are called from your
+board then the build will fail. Remove these calls and make a note of the
+init that needs to be done.
+
+
+7. Set up your platform data structure
+
+This will hold the information your driver to operate, like its hardware
+address or maximum frequency.
+
+You may already have a struct like this, or you may need to create one
+from some of the #defines or global variables in the driver.
+
+Note that this information is not the run-time information. It should not
+include state that changes. It should be fixed throughout the live of
+U-Boot. Run-time information comes later.
+
+Here is what was in the exynos spi driver:
+
+struct spi_bus {
+ enum periph_id periph_id;
+ s32 frequency; /* Default clock frequency, -1 for none */
+ struct exynos_spi *regs;
+ int inited; /* 1 if this bus is ready for use */
+ int node;
+ uint deactivate_delay_us; /* Delay to wait after deactivate */
+};
+
+Of these, inited is handled by DM and node is the device tree node, which
+DM tells you. The name is not quite right. So in this case we would use:
+
+struct exynos_spi_platdata {
+ enum periph_id periph_id;
+ s32 frequency; /* Default clock frequency, -1 for none */
+ struct exynos_spi *regs;
+ uint deactivate_delay_us; /* Delay to wait after deactivate */
+};
+
+
+8a. Write ofdata_to_platdata() [for device tree only]
+
+This method will convert information in the device tree node into a C
+structure in your driver (called platform data). If you are not using
+device tree, go to 8b.
+
+DM will automatically allocate the struct for us when we are using device
+tree, but we need to tell it the size:
+
+U_BOOT_DRIVER(spi_exynos) = {
+...
+ .platdata_auto_alloc_size = sizeof(struct exynos_spi_platdata),
+
+
+Here is a sample function. It gets a pointer to the platform data and
+fills in the fields from device tree.
+
+static int exynos_spi_ofdata_to_platdata(struct udevice *bus)
+{
+ struct exynos_spi_platdata *plat = bus->platdata;
+ const void *blob = gd->fdt_blob;
+ int node = bus->of_offset;
+
+ plat->regs = (struct exynos_spi *)fdtdec_get_addr(blob, node, "reg");
+ plat->periph_id = pinmux_decode_periph_id(blob, node);
+
+ if (plat->periph_id == PERIPH_ID_NONE) {
+ debug("%s: Invalid peripheral ID %d\n", __func__,
+ plat->periph_id);
+ return -FDT_ERR_NOTFOUND;
+ }
+
+ /* Use 500KHz as a suitable default */
+ plat->frequency = fdtdec_get_int(blob, node, "spi-max-frequency",
+ 500000);
+ plat->deactivate_delay_us = fdtdec_get_int(blob, node,
+ "spi-deactivate-delay", 0);
+ debug("%s: regs=%p, periph_id=%d, max-frequency=%d, deactivate_delay=%d\n",
+ __func__, plat->regs, plat->periph_id, plat->frequency,
+ plat->deactivate_delay_us);
+
+ return 0;
+}
+
+
+8b. Add the platform data [non-device-tree only]
+
+Specify this data in a U_BOOT_DEVICE() declaration in your board file:
+
+struct exynos_spi_platdata platdata_spi0 = {
+ .periph_id = ...
+ .frequency = ...
+ .regs = ...
+ .deactivate_delay_us = ...
+};
+
+U_BOOT_DEVICE(board_spi0) = {
+ .name = "exynos_spi",
+ .platdata = &platdata_spi0,
+};
+
+You will unfortunately need to put the struct into a header file in this
+case so that your board file can use it.
+
+
+9. Add the device private data
+
+Most devices have some private data which they use to keep track of things
+while active. This is the run-time information and needs to be stored in
+a structure. There is probably a structure in the driver that includes a
+'struct spi_slave', so you can use that.
+
+struct exynos_spi_slave {
+ struct spi_slave slave;
+ struct exynos_spi *regs;
+ unsigned int freq; /* Default frequency */
+ unsigned int mode;
+ enum periph_id periph_id; /* Peripheral ID for this device */
+ unsigned int fifo_size;
+ int skip_preamble;
+ struct spi_bus *bus; /* Pointer to our SPI bus info */
+ ulong last_transaction_us; /* Time of last transaction end */
+};
+
+
+We should rename this to make its purpose more obvious, and get rid of
+the slave structure, so we have:
+
+struct exynos_spi_priv {
+ struct exynos_spi *regs;
+ unsigned int freq; /* Default frequency */
+ unsigned int mode;
+ enum periph_id periph_id; /* Peripheral ID for this device */
+ unsigned int fifo_size;
+ int skip_preamble;
+ ulong last_transaction_us; /* Time of last transaction end */
+};
+
+
+DM can auto-allocate this also:
+
+U_BOOT_DRIVER(spi_exynos) = {
+...
+ .priv_auto_alloc_size = sizeof(struct exynos_spi_priv),
+
+
+Note that this is created before the probe method is called, and destroyed
+after the remove method is called. It will be zeroed when the probe
+method is called.
+
+
+10. Add the probe() and remove() methods
+
+Note: It's a good idea to build repeatedly as you are working, to avoid a
+huge amount of work getting things compiling at the end.
+
+The probe method is supposed to set up the hardware. U-Boot used to use
+spi_setup_slave() to do this. So take a look at this function and see
+what you can copy out to set things up.
+
+
+static int exynos_spi_probe(struct udevice *bus)
+{
+ struct exynos_spi_platdata *plat = dev_get_platdata(bus);
+ struct exynos_spi_priv *priv = dev_get_priv(bus);
+
+ priv->regs = plat->regs;
+ if (plat->periph_id == PERIPH_ID_SPI1 ||
+ plat->periph_id == PERIPH_ID_SPI2)
+ priv->fifo_size = 64;
+ else
+ priv->fifo_size = 256;
+
+ priv->skip_preamble = 0;
+ priv->last_transaction_us = timer_get_us();
+ priv->freq = plat->frequency;
+ priv->periph_id = plat->periph_id;
+
+ return 0;
+}
+
+This implementation doesn't actually touch the hardware, which is somewhat
+unusual for a driver. In this case we will do that when the device is
+claimed by something that wants to use the SPI bus.
+
+For remove we could shut down the clocks, but in this case there is
+nothing to do. DM frees any memory that it allocated, so we can just
+remove exynos_spi_remove() and its reference in U_BOOT_DRIVER.
+
+
+11. Implement set_speed()
+
+This should set up clocks so that the SPI bus is running at the right
+speed. With the old API spi_claim_bus() would normally do this and several
+of the following functions, so let's look at that function:
+
+int spi_claim_bus(struct spi_slave *slave)
+{
+ struct exynos_spi_slave *spi_slave = to_exynos_spi(slave);
+ struct exynos_spi *regs = spi_slave->regs;
+ u32 reg = 0;
+ int ret;
+
+ ret = set_spi_clk(spi_slave->periph_id,
+ spi_slave->freq);
+ if (ret < 0) {
+ debug("%s: Failed to setup spi clock\n", __func__);
+ return ret;
+ }
+
+ exynos_pinmux_config(spi_slave->periph_id, PINMUX_FLAG_NONE);
+
+ spi_flush_fifo(slave);
+
+ reg = readl(®s->ch_cfg);
+ reg &= ~(SPI_CH_CPHA_B | SPI_CH_CPOL_L);
+
+ if (spi_slave->mode & SPI_CPHA)
+ reg |= SPI_CH_CPHA_B;
+
+ if (spi_slave->mode & SPI_CPOL)
+ reg |= SPI_CH_CPOL_L;
+
+ writel(reg, ®s->ch_cfg);
+ writel(SPI_FB_DELAY_180, ®s->fb_clk);
+
+ return 0;
+}
+
+
+It sets up the speed, mode, pinmux, feedback delay and clears the FIFOs.
+With DM these will happen in separate methods.
+
+
+Here is an example for the speed part:
+
+static int exynos_spi_set_speed(struct udevice *bus, uint speed)
+{
+ struct exynos_spi_platdata *plat = bus->platdata;
+ struct exynos_spi_priv *priv = dev_get_priv(bus);
+ int ret;
+
+ if (speed > plat->frequency)
+ speed = plat->frequency;
+ ret = set_spi_clk(priv->periph_id, speed);
+ if (ret)
+ return ret;
+ priv->freq = speed;
+ debug("%s: regs=%p, speed=%d\n", __func__, priv->regs, priv->freq);
+
+ return 0;
+}
+
+
+12. Implement set_mode()
+
+This should adjust the SPI mode (polarity, etc.). Again this code probably
+comes from the old spi_claim_bus(). Here is an example:
+
+
+static int exynos_spi_set_mode(struct udevice *bus, uint mode)
+{
+ struct exynos_spi_priv *priv = dev_get_priv(bus);
+ uint32_t reg;
+
+ reg = readl(&priv->regs->ch_cfg);
+ reg &= ~(SPI_CH_CPHA_B | SPI_CH_CPOL_L);
+
+ if (mode & SPI_CPHA)
+ reg |= SPI_CH_CPHA_B;
+
+ if (mode & SPI_CPOL)
+ reg |= SPI_CH_CPOL_L;
+
+ writel(reg, &priv->regs->ch_cfg);
+ priv->mode = mode;
+ debug("%s: regs=%p, mode=%d\n", __func__, priv->regs, priv->mode);
+
+ return 0;
+}
+
+
+13. Implement claim_bus()
+
+This is where a client wants to make use of the bus, so claims it first.
+At this point we need to make sure everything is set up ready for data
+transfer. Note that this function is wholly internal to the driver - at
+present the SPI uclass never calls it.
+
+Here again we look at the old claim function and see some code that is
+needed. It is anything unrelated to speed and mode:
+
+static int exynos_spi_claim_bus(struct udevice *bus)
+{
+ struct exynos_spi_priv *priv = dev_get_priv(bus);
+
+ exynos_pinmux_config(priv->periph_id, PINMUX_FLAG_NONE);
+ spi_flush_fifo(priv->regs);
+
+ writel(SPI_FB_DELAY_180, &priv->regs->fb_clk);
+
+ return 0;
+}
+
+The spi_flush_fifo() function is in the removed part of the code, so we
+need to expose it again (perhaps with an #endif before it and '#if 0'
+after it). It only needs access to priv->regs which is why we have
+passed that in:
+
+/**
+ * Flush spi tx, rx fifos and reset the SPI controller
+ *
+ * @param regs Pointer to SPI registers
+ */
+static void spi_flush_fifo(struct exynos_spi *regs)
+{
+ clrsetbits_le32(®s->ch_cfg, SPI_CH_HS_EN, SPI_CH_RST);
+ clrbits_le32(®s->ch_cfg, SPI_CH_RST);
+ setbits_le32(®s->ch_cfg, SPI_TX_CH_ON | SPI_RX_CH_ON);
+}
+
+
+14. Implement release_bus()
+
+This releases the bus - in our example the old code in spi_release_bus()
+is a call to spi_flush_fifo, so we add:
+
+static int exynos_spi_release_bus(struct udevice *bus)
+{
+ struct exynos_spi_priv *priv = dev_get_priv(bus);
+
+ spi_flush_fifo(priv->regs);
+
+ return 0;
+}
+
+
+15. Implement xfer()
+
+This is the final method that we need to create, and it is where all the
+work happens. The method parameters are the same as the old spi_xfer() with
+the addition of a 'struct udevice' so conversion is pretty easy. Start
+by copying the contents of spi_xfer() to your new xfer() method and proceed
+from there.
+
+If (flags & SPI_XFER_BEGIN) is non-zero then xfer() normally calls an
+activate function, something like this:
+
+void spi_cs_activate(struct spi_slave *slave)
+{
+ struct exynos_spi_slave *spi_slave = to_exynos_spi(slave);
+
+ /* If it's too soon to do another transaction, wait */
+ if (spi_slave->bus->deactivate_delay_us &&
+ spi_slave->last_transaction_us) {
+ ulong delay_us; /* The delay completed so far */
+ delay_us = timer_get_us() - spi_slave->last_transaction_us;
+ if (delay_us < spi_slave->bus->deactivate_delay_us)
+ udelay(spi_slave->bus->deactivate_delay_us - delay_us);
+ }
+
+ clrbits_le32(&spi_slave->regs->cs_reg, SPI_SLAVE_SIG_INACT);
+ debug("Activate CS, bus %d\n", spi_slave->slave.bus);
+ spi_slave->skip_preamble = spi_slave->mode & SPI_PREAMBLE;
+}
+
+The new version looks like this:
+
+static void spi_cs_activate(struct udevice *dev)
+{
+ struct udevice *bus = dev->parent;
+ struct exynos_spi_platdata *pdata = dev_get_platdata(bus);
+ struct exynos_spi_priv *priv = dev_get_priv(bus);
+
+ /* If it's too soon to do another transaction, wait */
+ if (pdata->deactivate_delay_us &&
+ priv->last_transaction_us) {
+ ulong delay_us; /* The delay completed so far */
+ delay_us = timer_get_us() - priv->last_transaction_us;
+ if (delay_us < pdata->deactivate_delay_us)
+ udelay(pdata->deactivate_delay_us - delay_us);
+ }
+
+ clrbits_le32(&priv->regs->cs_reg, SPI_SLAVE_SIG_INACT);
+ debug("Activate CS, bus '%s'\n", bus->name);
+ priv->skip_preamble = priv->mode & SPI_PREAMBLE;
+}
+
+All we have really done here is change the pointers and print the device name
+instead of the bus number. Other local static functions can be treated in
+the same way.
+
+
+16. Set up the per-child data and child pre-probe function
+
+To minimise the pain and complexity of the SPI subsystem while the driver
+model change-over is in place, struct spi_slave is used to reference a
+SPI bus slave, even though that slave is actually a struct udevice. In fact
+struct spi_slave is the device's child data. We need to make sure this space
+is available. It is possible to allocate more space that struct spi_slave
+needs, but this is the minimum.
+
+U_BOOT_DRIVER(exynos_spi) = {
+...
+ .per_child_auto_alloc_size = sizeof(struct spi_slave),
+}
+
+
+17. Optional: Set up cs_info() if you want it
+
+Sometimes it is useful to know whether a SPI chip select is valid, but this
+is not obvious from outside the driver. In this case you can provide a
+method for cs_info() to deal with this. If you don't provide it, then the
+device tree will be used to determine what chip selects are valid.
+
+Return -ENODEV if the supplied chip select is invalid, or 0 if it is valid.
+If you don't provide the cs_info() method, -ENODEV is assumed for all
+chip selects that do not appear in the device tree.
+
+
+18. Test it
+
+Now that you have the code written and it compiles, try testing it using
+the 'sf test' command. You may need to enable CONFIG_CMD_SF_TEST for your
+board.
+
+
+19. Prepare patches and send them to the mailing lists
+
+You can use 'tools/patman/patman' to prepare, check and send patches for
+your work. See the README for details.

+Booting Linux on x86 with FIT
+=============================
+
+Background
+----------
+
+(corrections to the text below are welcome)
+
+Generally Linux x86 uses its own very complex booting method. There is a setup
+binary which contains all sorts of parameters and a compressed self-extracting
+binary for the kernel itself, often with a small built-in serial driver to
+display decompression progress.
+
+The x86 CPU has various processor modes. I am no expert on these, but my
+understanding is that an x86 CPU (even a really new one) starts up in a 16-bit
+'real' mode where only 1MB of memory is visible, moves to 32-bit 'protected'
+mode where 4GB is visible (or more with special memory access techniques) and
+then to 64-bit 'long' mode if 64-bit execution is required.
+
+Partly the self-extracting nature of Linux was introduced to cope with boot
+loaders that were barely capable of loading anything. Even changing to 32-bit
+mode was something of a challenge, so putting this logic in the kernel seemed
+to make sense.
+
+Bit by bit more and more logic has been added to this post-boot pre-Linux
+wrapper:
+
+- Changing to 32-bit mode
+- Decompression
+- Serial output (with drivers for various chips)
+- Load address randomisation
+- Elf loader complete with relocation (for the above)
+- Random number generator via 3 methods (again for the above)
+- Some sort of EFI mini-loader (1000+ glorious lines of code)
+- Locating and tacking on a device tree and ramdisk
+
+To my mind, if you sit back and look at things from first principles, this
+doesn't make a huge amount of sense. Any boot loader worth its salts already
+has most of the above features and more besides. The boot loader already knows
+the layout of memory, has a serial driver, can decompress things, includes an
+ELF loader and supports device tree and ramdisks. The decision to duplicate
+all these features in a Linux wrapper caters for the lowest common
+denominator: a boot loader which consists of a BIOS call to load something off
+disk, followed by a jmp instruction.
+
+(Aside: On ARM systems, we worry that the boot loader won't know where to load
+the kernel. It might be easier to just provide that information in the image,
+or in the boot loader rather than adding a self-relocator to put it in the
+right place. Or just use ELF?
+
+As a result, the x86 kernel boot process is needlessly complex. The file
+format is also complex, and obfuscates the contents to a degree that it is
+quite a challenge to extract anything from it. This bzImage format has become
+so prevalent that is actually isn't possible to produce the 'raw' kernel build
+outputs with the standard Makefile (as it is on ARM for example, at least at
+the time of writing).
+
+This document describes an alternative boot process which uses simple raw
+images which are loaded into the right place by the boot loader and then
+executed.
+
+
+Build the kernel
+----------------
+
+Note: these instructions assume a 32-bit kernel. U-Boot does not currently
+support booting a 64-bit kernel as it has no way of going into 64-bit mode on
+x86.
+
+You can build the kernel as normal with 'make'. This will create a file called
+'vmlinux'. This is a standard ELF file and you can look at it if you like:
+
+$ objdump -h vmlinux
+
+vmlinux: file format elf32-i386

+line and various settings need by the kernel. Arguably the boot loader should
+provide all of this also, but setting it up is some complex that the kernel
+helps by providing a head start.
+
+As you can see the code loads to address 0x01000000 and everything else
+follows after that. We could load this image using the 'bootelf' command but
+we would still need to provide the setup binary. This is not supported by
+U-Boot although I suppose you could mostly script it. This would permit the
+use of a relocatable kernel.
+
+All we need to boot is the vmlinux file and the setup.bin file.
+
+
+Create a FIT
+------------
+
+To create a FIT you will need a source file describing what should go in the
+FIT. See kernel.its for an example for x86. Put this into a file called
+image.its.
+
+Note that setup is loaded to the special address of 0x90000 (a special address
+you just have to know) and the kernel is loaded to 0x01000000 (the address you
+saw above). This means that you will need to load your FIT to a different
+address so that U-Boot doesn't overwrite it when decompressing. Something like
+0x02000000 will do so you can set CONFIG_SYS_LOAD_ADDR to that.
+
+In that example the kernel is compressed with lzo. Also we need to provide a
+flat binary, not an ELF. So the steps needed to set things are are:
+
+ # Create a flat binary
+ objcopy -O binary vmlinux vmlinux.bin
+
+ # Compress it into LZO format
+ lzop vmlinux.bin
+
+ # Build a FIT image
+ mkimage -f image.its image.fit
+
+(be careful to run the mkimage from your U-Boot tools directory since it
+will have x86_setup support.)
+
+You can take a look at the resulting fit file if you like:
+
+$ dumpimage -l image.fit

+
+
+Booting the FIT
+---------------
+
+To make it boot you need to load it and then use 'bootm' to boot it. A
+suitable script to do this from a network server is:
+
+ bootp
+ tftp image.fit
+ bootm
+
+This will load the image from the network and boot it. The command line (from
+the 'bootargs' environment variable) will be passed to the kernel.
+
+If you want a ramdisk you can add it as normal with FIT. If you want a device
+tree then x86 doesn't normally use those - it has ACPI instead.
+
+
+Why Bother?
+-----------
+
+1. It demystifies the process of booting an x86 kernel
+2. It allows use of the standard U-Boot boot file format
+3. It allows U-Boot to perform decompression - problems will provide an error
+message and you are still in the boot loader. It is possible to investigate.
+4. It avoids all the pre-loader code in the kernel which is quite complex to
+follow
+5. You can use verified/secure boot and other features which haven't yet been
+added to the pre-Linux
+6. It makes x86 more like other architectures in the way it boots a kernel.
+You can potentially use the same file format for the kernel, and the same
+procedure for building and packaging it.
+
+
+References
+----------
+
+In the Linux kernel, Documentation/x86/boot.txt defines the boot protocol for
+the kernel including the setup.bin format. This is handled in U-Boot in
+arch/x86/lib/zimage.c and arch/x86/lib/bootm.c.
+
+The procedure for entering 64-bit mode on x86 seems to be described here:
+
+ http://wiki.osdev.org/64-bit_Higher_Half_Kernel_with_GRUB_2
+
+Various files in the same directory as this file describe the FIT format.
