- CONFIG_SYS_MALLOC_LEN:
Size of DRAM reserved for malloc() use.
+- CONFIG_SYS_MALLOC_F_LEN
+ Size of the malloc() pool for use before relocation. If
+ this is defined, then a very simple malloc() implementation
+ will become available before relocation. The address is just
+ below the global data, and the stack is moved down to make
+ space.
+
+ This feature allocates regions with increasing addresses
+ within the region. calloc() is supported, but realloc()
+ is not available. free() is supported but does nothing.
+ The memory will be freed (or in fact just forgotton) when
+ U-Boot relocates itself.
+
+ Pre-relocation malloc() is only supported on sandbox
+ at present but is fairly easy to enable for other archs.
+
- CONFIG_SYS_BOOTM_LEN:
Normally compressed uImages are limited to an
uncompressed size of 8 MBytes. If this is not enough,
if (cooked_str != raw_str)
free((char *)cooked_str);

What is going on?
-----------------
end of the enum there, then declare your uclass as above.
+Device Sequence Numbers
+-----------------------
+
+U-Boot numbers devices from 0 in many situations, such as in the command
+line for I2C and SPI buses, and the device names for serial ports (serial0,
+serial1, ...). Driver model supports this numbering and permits devices
+to be locating by their 'sequence'.
+
+Sequence numbers start from 0 but gaps are permitted. For example, a board
+may have I2C buses 0, 1, 4, 5 but no 2 or 3. The choice of how devices are
+numbered is up to a particular board, and may be set by the SoC in some
+cases. While it might be tempting to automatically renumber the devices
+where there are gaps in the sequence, this can lead to confusion and is
+not the way that U-Boot works.
+
+Each device can request a sequence number. If none is required then the
+device will be automatically allocated the next available sequence number.
+
+To specify the sequence number in the device tree an alias is typically
+used.
+
+aliases {
+ serial2 = "/serial@22230000";
+};
+
+This indicates that in the uclass called "serial", the named node
+("/serial@22230000") will be given sequence number 2. Any command or driver
+which requests serial device 2 will obtain this device.
+
+Some devices represent buses where the devices on the bus are numbered or
+addressed. For example, SPI typically numbers its slaves from 0, and I2C
+uses a 7-bit address. In these cases the 'reg' property of the subnode is
+used, for example:
+
+{
+ aliases {
+ spi2 = "/spi@22300000";
+ };
+
+ spi@22300000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ spi-flash@0 {
+ reg = <0>;
+ ...
+ }
+ eeprom@1 {
+ reg = <1>;
+ };
+ };
+
+In this case we have a SPI bus with two slaves at 0 and 1. The SPI bus
+itself is numbered 2. So we might access the SPI flash with:
+
+ sf probe 2:0
+
+and the eeprom with
+
+ sspi 2:1 32 ef
+
+These commands simply need to look up the 2nd device in the SPI uclass to
+find the right SPI bus. Then, they look at the children of that bus for the
+right sequence number (0 or 1 in this case).
+
+Typically the alias method is used for top-level nodes and the 'reg' method
+is used only for buses.
+
+Device sequence numbers are resolved when a device is probed. Before then
+the sequence number is only a request which may or may not be honoured,
+depending on what other devices have been probed. However the numbering is
+entirely under the control of the board author so a conflict is generally
+an error.
+
+
+Bus Drivers
+-----------
+
+A common use of driver model is to implement a bus, a device which provides
+access to other devices. Example of buses include SPI and I2C. Typically
+the bus provides some sort of transport or translation that makes it
+possible to talk to the devices on the bus.
+
+Driver model provides a few useful features to help with implementing
+buses. Firstly, a bus can request that its children store some 'parent
+data' which can be used to keep track of child state. Secondly, the bus can
+define methods which are called when a child is probed or removed. This is
+similar to the methods the uclass driver provides.
+
+Here an explanation of how a bus fits with a uclass may be useful. Consider
+a USB bus with several devices attached to it, each from a different (made
+up) uclass:
+
+ xhci_usb (UCLASS_USB)
+ eth (UCLASS_ETHERNET)
+ camera (UCLASS_CAMERA)
+ flash (UCLASS_FLASH_STORAGE)
+
+Each of the devices is connected to a different address on the USB bus.
+The bus device wants to store this address and some other information such
+as the bus speed for each device.
+
+To achieve this, the bus device can use dev->parent_priv in each of its
+three children. This can be auto-allocated if the bus driver has a non-zero
+value for per_child_auto_alloc_size. If not, then the bus device can
+allocate the space itself before the child device is probed.
+
+Also the bus driver can define the child_pre_probe() and child_post_remove()
+methods to allow it to do some processing before the child is activated or
+after it is deactivated.
+
+Note that the information that controls this behaviour is in the bus's
+driver, not the child's. In fact it is possible that child has no knowledge
+that it is connected to a bus. The same child device may even be used on two
+different bus types. As an example. the 'flash' device shown above may also
+be connected on a SATA bus or standalone with no bus:
+
+ xhci_usb (UCLASS_USB)
+ flash (UCLASS_FLASH_STORAGE) - parent data/methods defined by USB bus
+
+ sata (UCLASS_SATA)
+ flash (UCLASS_FLASH_STORAGE) - parent data/methods defined by SATA bus
+
+ flash (UCLASS_FLASH_STORAGE) - no parent data/methods (not on a bus)
+
+Above you can see that the driver for xhci_usb/sata controls the child's
+bus methods. In the third example the device is not on a bus, and therefore
+will not have these methods at all. Consider the case where the flash
+device defines child methods. These would be used for *its* children, and
+would be quite separate from the methods defined by the driver for the bus
+that the flash device is connetced to. The act of attaching a device to a
+parent device which is a bus, causes the device to start behaving like a
+bus device, regardless of its own views on the matter.
+
+The uclass for the device can also contain data private to that uclass.
+But note that each device on the bus may be a memeber of a different
+uclass, and this data has nothing to do with the child data for each child
+on the bus.
+
+
Driver Lifecycle

stored in the device, but it is uclass data. owned by the uclass driver.
It is possible for the device to access it.
- d. All parent devices are probed. It is not possible to activate a device
+ d. If the device's immediate parent specifies a per_child_auto_alloc_size
+ then this space is allocated. This is intended for use by the parent
+ device to keep track of things related to the child. For example a USB
+ flash stick attached to a USB host controller would likely use this
+ space. The controller can hold information about the USB state of each
+ of its children.
+
+ e. All parent devices are probed. It is not possible to activate a device
unless its predecessors (all the way up to the root device) are activated.
This means (for example) that an I2C driver will require that its bus
be activated.

+ f. The device's sequence number is assigned, either the requested one
+ (assuming no conflicts) or the next available one if there is a conflict
+ or nothing particular is requested.
+
+ g. If the driver provides an ofdata_to_platdata() method, then this is
called to convert the device tree data into platform data. This should
do various calls like fdtdec_get_int(gd->fdt_blob, dev->of_offset, ...)
to access the node and store the resulting information into dev->platdata.

platdata_auto_alloc_size. Remember to free them in the remove() method.

+
+ f. The device is marked inactive. Note that it is still bound, so the
device structure itself is not freed at this point. Should the device be

+Pre-Relocation Support
+----------------------
+
+For pre-relocation we simply call the driver model init function. Only
+drivers marked with DM_FLAG_PRE_RELOC or the device tree
+'u-boot,dm-pre-reloc' flag are initialised prior to relocation. This helps
+to reduce the driver model overhead.
+
+Then post relocation we throw that away and re-init driver model again.
+For drivers which require some sort of continuity between pre- and
+post-relocation devices, we can provide access to the pre-relocation
+device pointers, but this is not currently implemented (the root device
+pointer is saved but not made available through the driver model API).
+
+
Things to punt for later
------------------------
- SPL support - this will have to be present before many drivers can be
converted, but it seems like we can add it once we are happy with the
core implementation.
-- Pre-relocation support - similar story
-That is not to say that no thinking has gone into these - in fact there
+That is not to say that no thinking has gone into this - in fact there
is quite a lot there. However, getting these right is non-trivial and
there is a high cost associated with going down the wrong path.
For SPL, it may be possible to fit in a simplified driver model with only
bind and probe methods, to reduce size.
-For pre-relocation we can simply call the driver model init function. Then
-post relocation we throw that away and re-init driver model again. For drivers
-which require some sort of continuity between pre- and post-relocation
-devices, we can provide access to the pre-relocation device pointers.

Uclasses are statically numbered at compile time. It would be possible to
change this to dynamic numbering, but then we would require some sort of
lookup service, perhaps searching by name. This is slightly less efficient

+A tool to create/update the mailmap file
+
+The command 'git shortlog' summarizes git log output in a format suitable
+for inclusion in release announcements. Each commit will be grouped by
+author and title.
+
+One problem is that the authors' name and/or email address is sometimes
+spelled differently. The .mailmap feature can be used to coalesce together
+commits by the same persion.
+(See 'man git-shortlog' for furthur information of this feature.)
+
+This tool helps to create/update the mailmap file.
+
+It runs 'git shortlog' internally and searches differently spelled author
+names which share the same email address. The author name with the most
+commits is asuumed to be a canonical real name. If the number of commits
+from the cananonical name is equal to or greater than 'MIN_COMMITS',
+the entry for the cananical name will be output. ('MIN_COMMITS' is used
+here because we do not want to create a fat mailmap by adding every author
+with only a few commits.)
+
+If there exists a mailmap file specified by the mailmap.file configuration
+options or '.mailmap' at the toplevel of the repository, it is used as
+a base file. (The mailmap.file configuration takes precedence over the
+'.mailmap' file if both exist.)
+
+The base file and the newly added entries are merged together and sorted
+alphabetically (but the comment block is kept untouched), and then printed
+to standard output.
+
+Usage
+-----
+
+ scripts/mailmapper
+
+prints the mailmapping to standard output.
+
+ scripts/mailmapper > tmp; mv tmp .mailmap
