What is CRIS ?
--------------
CRIS is an acronym for 'Code Reduced Instruction Set'. It is the CPU
architecture in Axis Communication AB's range of embedded network CPU's,
-called ETRAX. The latest CPU is called ETRAX 100LX, where LX stands for
-'Linux' because the chip was designed to be a good host for the Linux
-operating system.
+called ETRAX.
The ETRAX 100LX chip
--------------------
-For reference, please see the press-release:
+For reference, please see the following link:

-The previous version of the ETRAX, the ETRAX 100, sits in almost all of
-Axis shipping thin-servers like the Axis 2100 web camera or the ETRAX 100
-developer-board. It lacks an MMU so the Linux we run on that is a version
-of uClinux (Linux 2.0 without MM-support) ported to the CRIS architecture.
-The new Linux 2.4 port has full MM and needs a CPU with an MMU, so it will
-not run on the ETRAX 100.
+ETRAX 100LX is CRISv10 architecture.
+
+
+The ETRAX FS and ARTPEC-3 chips
+-------------------------------
-A version of the Axis developer-board with ETRAX 100LX (running Linux
-2.4) is now available. For more information please see developer.axis.com.
+The ETRAX FS is a 200MHz 32-bit RISC processor with on-chip 16kB
+I-cache and 16kB D-cache and with a wide range of device interfaces
+including multiple high speed serial ports and an integrated USB 1.1 PHY.
+The ARTPEC-3 is a variant of the ETRAX FS with additional IO-units
+used by the Axis Communications network cameras.
+
+See below link for more information:

+Device State Configuration Registers
+------------------------------------
+
+TI C6X SoCs contain a region of miscellaneous registers which provide various
+function for SoC control or status. Details vary considerably among from SoC
+to SoC with no two being alike.
+
+In general, the Device State Configuraion Registers (DSCR) will provide one or
+more configuration registers often protected by a lock register where one or
+more key values must be written to a lock register in order to unlock the
+configuration register for writes. These configuration register may be used to
+enable (and disable in some cases) SoC pin drivers, select peripheral clock
+sources (internal or pin), etc. In some cases, a configuration register is
+write once or the individual bits are write once. In addition to device config,
+the DSCR block may provide registers which which are used to reset peripherals,
+provide device ID information, provide ethernet MAC addresses, as well as other
+miscellaneous functions.
+
+For device state control (enable/disable), each device control is assigned an
+id which is used by individual device drivers to control the state as needed.
+
+Required properties:
+
+- compatible: must be "ti,c64x+dscr"
+- reg: register area base and size
+
+Optional properties:
+
+ NOTE: These are optional in that not all SoCs will have all properties. For
+ SoCs which do support a given property, leaving the property out of the
+ device tree will result in reduced functionality or possibly driver
+ failure.
+

+
+- ti,dscr-silicon-rev
+ offset, start bit, and bitsize of silicon revision field
+

+ offset and bitmask of RMII reset field. May have multiple tuples if more
+ than one ethernet port is available.
+
+- ti,dscr-locked-regs
+ possibly multiple tuples describing registers which are write protected by
+ a lock register. Each tuple consists of the register offset, lock register
+ offsset, and the key value used to unlock the register.
+
+- ti,dscr-kick-regs
+ offset and key values of two "kick" registers used to write protect other
+ registers in DSCR. On SoCs using kick registers, the first key must be
+ written to the first kick register and the second key must be written to
+ the second register before other registers in the area are write-enabled.
+
+- ti,dscr-mac-fuse-regs
+ MAC addresses are contained in two registers. Each element of a MAC address
+ is contained in a single byte. This property has two tuples. Each tuple has
+ a register offset and four cells representing bytes in the register from
+ most significant to least. The value of these four cells is the MAC byte
+ index (1-6) of the byte within the register. A value of 0 means the byte
+ is unused in the MAC address.
+
+- ti,dscr-devstate-ctl-regs
+ This property describes the bitfields used to control the state of devices.
+ Each tuple describes a range of identical bitfields used to control one or
+ more devices (one bitfield per device). The layout of each tuple is:
+
+ start_id num_ids reg enable disable start_bit nbits
+
+ Where:
+ start_id is device id for the first device control in the range
+ num_ids is the number of device controls in the range
+ reg is the offset of the register holding the control bits
+ enable is the value to enable a device
+ disable is the value to disable a device (0xffffffff if cannot disable)
+ start_bit is the bit number of the first bit in the range
+ nbits is the number of bits per device control
+
+- ti,dscr-devstate-stat-regs
+ This property describes the bitfields used to provide device state status
+ for device states controlled by the DSCR. Each tuple describes a range of
+ identical bitfields used to provide status for one or more devices (one
+ bitfield per device). The layout of each tuple is:
+
+ start_id num_ids reg enable disable start_bit nbits
+
+ Where:
+ start_id is device id for the first device status in the range
+ num_ids is the number of devices covered by the range
+ reg is the offset of the register holding the status bits
+ enable is the value indicating device is enabled
+ disable is the value indicating device is disabled
+ start_bit is the bit number of the first bit in the range
+ nbits is the number of bits per device status
+
+- ti,dscr-privperm
+ Offset and default value for register used to set access privilege for
+ some SoC devices.

+C6X Interrupt Chips
+-------------------
+
+* C64X+ Core Interrupt Controller
+
+ The core interrupt controller provides 16 prioritized interrupts to the
+ C64X+ core. Priority 0 and 1 are used for reset and NMI respectively.
+ Priority 2 and 3 are reserved. Priority 4-15 are used for interrupt
+ sources coming from outside the core.
+
+ Required properties:
+ --------------------
+ - compatible: Should be "ti,c64x+core-pic";
+ - #interrupt-cells: <1>
+
+ Interrupt Specifier Definition
+ ------------------------------
+ Single cell specifying the core interrupt priority level (4-15) where
+ 4 is highest priority and 15 is lowest priority.
+
+ Example
+ -------
+ core_pic: interrupt-controller@0 {
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ compatible = "ti,c64x+core-pic";
+ };
+
+
+
+* C64x+ Megamodule Interrupt Controller
+
+ The megamodule PIC consists of four interrupt mupliplexers each of which
+ combine up to 32 interrupt inputs into a single interrupt output which
+ may be cascaded into the core interrupt controller. The megamodule PIC
+ has a total of 12 outputs cascading into the core interrupt controller.
+ One for each core interrupt priority level. In addition to the combined
+ interrupt sources, individual megamodule interrupts may be cascaded to
+ the core interrupt controller. When an individual interrupt is cascaded,
+ it is no longer handled through a megamodule interrupt combiner and is
+ considered to have the core interrupt controller as the parent.
+
+ Required properties:
+ --------------------
+ - compatible: "ti,c64x+megamod-pic"
+ - interrupt-controller
+ - #interrupt-cells: <1>
+ - reg: base address and size of register area
+ - interrupt-parent: must be core interrupt controller
+ - interrupts: This should have four cells; one for each interrupt combiner.
+ The cells contain the core priority interrupt to which the
+ corresponding combiner output is wired.
+
+ Optional properties:
+ --------------------
+ - ti,c64x+megamod-pic-mux: Array of 12 cells correspnding to the 12 core
+ priority interrupts. The first cell corresponds to
+ core priority 4 and the last cell corresponds to
+ core priority 15. The value of each cell is the
+ megamodule interrupt source which is MUXed to
+ the core interrupt corresponding to the cell
+ position. Allowed values are 4 - 127. Mapping for
+ interrupts 0 - 3 (combined interrupt sources) are
+ ignored.
+
+ Interrupt Specifier Definition
+ ------------------------------
+ Single cell specifying the megamodule interrupt source (4-127). Note that
+ interrupts mapped directly to the core with "ti,c64x+megamod-pic-mux" will
+ use the core interrupt controller as their parent and the specifier will
+ be the core priority level, not the megamodule interrupt number.
+
+ Examples
+ --------
+ megamod_pic: interrupt-controller@1800000 {
+ compatible = "ti,c64x+megamod-pic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x1800000 0x1000>;
+ interrupt-parent = <&core_pic>;
+ interrupts = < 12 13 14 15 >;
+ };
+
+ This is a minimal example where all individual interrupts go through a
+ combiner. Combiner-0 is mapped to core interrupt 12, combiner-1 is mapped
+ to interrupt 13, etc.
+
+
+ megamod_pic: interrupt-controller@1800000 {
+ compatible = "ti,c64x+megamod-pic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x1800000 0x1000>;
+ interrupt-parent = <&core_pic>;
+ interrupts = < 12 13 14 15 >;
+ ti,c64x+megamod-pic-mux = < 0 0 0 0
+ 32 0 0 0
+ 0 0 0 0 >;
+ };
+
+ This the same as the first example except that megamodule interrupt 32 is
+ mapped directly to core priority interrupt 8. The node using this interrupt
+ must set the core controller as its interrupt parent and use 8 in the
+ interrupt specifier value.

+as shown below.
+
+ [property name] = <[phandle of the dma controller] [dma request id]>;
+

+* Samsung's S3C Real Time Clock controller
+
+Required properties:
+- compatible: should be one of the following.
+ * "samsung,s3c2410-rtc" - for controllers compatible with s3c2410 rtc.
+ * "samsung,s3c6410-rtc" - for controllers compatible with s3c6410 rtc.
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: Two interrupt numbers to the cpu should be specified. First
+ interrupt number is the rtc alarm interupt and second interrupt number
+ is the rtc tick interrupt. The number of cells representing a interrupt
+ depends on the parent interrupt controller.
+
+Example:
+
+ rtc@10070000 {
+ compatible = "samsung,s3c6410-rtc";
+ reg = <0x10070000 0x100>;
+ interrupts = <44 0 45 0>;
+ };
--- /dev/null
+* Samsung's UART Controller
+
+The Samsung's UART controller is used for interfacing SoC with serial communicaion
+devices.
+
+Required properties:
+- compatible: should be
+ - "samsung,exynos4210-uart", for UART's compatible with Exynos4210 uart ports.
+
+- reg: base physical address of the controller and length of memory mapped
+ region.
+
+- interrupts: interrupt number to the cpu. The interrupt specifier format depends
+ on the interrupt controller parent.

+Tegra SOC USB controllers
+
+The device node for a USB controller that is part of a Tegra
+SOC is as described in the document "Open Firmware Recommended
+Practice : Universal Serial Bus" with the following modifications
+and additions :
+
+Required properties :
+ - compatible : Should be "nvidia,tegra20-ehci" for USB controllers
+ used in host mode.
+ - phy_type : Should be one of "ulpi" or "utmi".
+ - nvidia,vbus-gpio : If present, specifies a gpio that needs to be
+ activated for the bus to be powered.

+ help
+ If a data is stalled inside asynchronous bridge because of back
+ pressure, it may be accepted multiple times, creating pointer
+ misalignment that will corrupt next transfers on that data path
+ until next reset of the system (No recovery procedure once the
+ issue is hit, the path remains consistently broken). Async bridge
+ can be found on path between MPU to EMIF and MPU to L3 interconnect.
+ This situation can happen only when the idle is initiated by a
+ Master Request Disconnection (which is trigged by software when
+ executing WFI on CPU).
+ The work-around for this errata needs all the initiators connected
+ through async bridge must ensure that data path is properly drained
+ before issuing WFI. This condition will be met if one Strongly ordered
+ access is performed to the target right before executing the WFI.
+ In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained.
+ IO barrier ensure that there is no synchronisation loss on initiators
+ operating on both interconnect port simultaneously.

+ bool "Build a big kernel"
+ help
+ The C6X function call instruction has a limited range of +/- 2MiB.
+ This is sufficient for most kernels, but some kernel configurations
+ with lots of compiled-in functionality may require a larger range
+ for function calls. Use this option to have the compiler generate
+ function calls with 32-bit range. This will make the kernel both
+ larger and slower.
+
+ If unsure, say N.

+ of your chipset/board/processor.
+
+config FORCE_MAX_ZONEORDER
+ int "Maximum zone order"
+ default "13"
+ help
+ The kernel memory allocator divides physically contiguous memory
+ blocks into "zones", where each zone is a power of two number of
+ pages. This option selects the largest power of two that the kernel
+ keeps in the memory allocator. If you need to allocate very large
+ blocks of physically contiguous memory, then you may need to
+ increase this value.
+
+ This config option is actually maximum order plus one. For example,
+ a value of 11 means that the largest free memory block is 2^10 pages.

- * interrupts. When any slot IRQ is disabled we mask the (edge triggered) CA1
- * or "SLOTS" interrupt. When no slot is disabled, we unmask the CA1 interrupt.
- * So, on genuine VIAs, having more than one NuBus IRQ can mean trouble,
- * because closing one of those drivers can mask all of the NuBus interrupts.
- * Also, since we can't mask the unregistered slot IRQs on genuine VIAs, it's
- * possible to get interrupts from cards that MacOS or the ROM has configured
- * but we have not. FWIW, "Designing Cards and Drivers for Macintosh II and
- * Macintosh SE", page 9-8, says, a slot IRQ with no driver would crash MacOS.
+
+/*
+ * On Macs with a genuine VIA chip there is no way to mask an individual slot
+ * interrupt. This limitation also seems to apply to VIA clone logic cores in
+ * Quadra-like ASICs. (RBV and OSS machines don't have this limitation.)
+ *
+ * We used to fake it by configuring the relevent VIA pin as an output
+ * (to mask the interrupt) or input (to unmask). That scheme did not work on
+ * (at least) the Quadra 700. A NuBus card's /NMRQ signal is an open-collector
+ * circuit (see Designing Cards and Drivers for Macintosh II and Macintosh SE,
+ * p. 10-11 etc) but VIA outputs are not (see datasheet).
+ *
+ * Driving these outputs high must cause the VIA to source current and the
+ * card to sink current when it asserts /NMRQ. Current will flow but the pin
+ * voltage is uncertain and so the /NMRQ condition may still cause a transition
+ * at the VIA2 CA1 input (which explains the lost interrupts). A side effect
+ * is that a disabled slot IRQ can never be tested as pending or not.
+ *
+ * Driving these outputs low doesn't work either. All the slot /NMRQ lines are
+ * (active low) OR'd together to generate the CA1 (aka "SLOTS") interrupt (see
+ * The Guide To Macintosh Family Hardware, 2nd edition p. 167). If we drive a
+ * disabled /NMRQ line low, the falling edge immediately triggers a CA1
+ * interrupt and all slot interrupts after that will generate no transition
+ * and therefore no interrupt, even after being re-enabled.
+ *
+ * So we make the VIA port A I/O lines inputs and use nubus_disabled to keep
+ * track of their states. When any slot IRQ becomes disabled we mask the CA1
+ * umbrella interrupt. Only when all slot IRQs become enabled do we unmask
+ * the CA1 interrupt. It must remain enabled even when cards have no interrupt
+ * handler registered. Drivers must therefore disable a slot interrupt at the
+ * device before they call free_irq (like shared and autovector interrupts).
+ *
+ * There is also a related problem when MacOS is used to boot Linux. A network
+ * card brought up by a MacOS driver may raise an interrupt while Linux boots.
+ * This can be fatal since it can't be handled until the right driver loads
+ * (if such a driver exists at all). Apparently related to this hardware
+ * limitation, "Designing Cards and Drivers", p. 9-8, says that a slot
+ * interrupt with no driver would crash MacOS (the book was written before
+ * the appearance of Macs with RBV or OSS).
