For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.

The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:

master:
	1. NOR flash for its own u-boot image, ucode and ENV space.
	2. Slave's u-boot image in master NOR flash.
	3. Normally boot from local NOR flash.
	4. Configure SRIO switch system if needed.
slave:
	1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
	2. Boot location should be set to SRIO1 or SRIO2 by RCW.
	3. RCW should configure the SerDes, SRIO interfaces correctly.
	4. Slave must be powered on after master's boot.
	5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode
	   locally.

For the slave module, need to finish these processes:
	1. Set the boot location to SRIO1 or SRIO2 by RCW.
    2. Set a specific TLB entry for the boot process.
	3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot.
	4. Slave's u-boot image should be generated specifically by
	   make xxxx_SRIOBOOT_SLAVE_config.
	   This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

The original ld script line arch/powerpc/cpu/mpc85xx/start.o

In the p1023rds, when system boots from nor flash, kernel only accesses nor
flash and can not access nand flash with BR0/OR0; when system boots from
nand flash, kernel only accesses nand flash and can not access nor flash
with BR0/OR0.

Default device tree nor and nand node should have the following structure:

	Example:

		nor_flash: nor@0,0 {
			#address-cells = <1>;
			#size-cells = <1>;
			compatible = "cfi-flash";
			reg = <0x0 0x0 0x02000000>;
			bank-width = <2>;
			device-width = <1>;
			status = "okay";

			partition@0 {
				label = "ramdisk";
				reg = <0x00000000 0x01c00000>;
			};
		}

		nand_flash: nand@1,0 {
			#address-cells = <1>;
			#size-cells = <1>;
			compatible = "fsl,p1023-fcm-nand",
				     "fsl,elbc-fcm-nand";
			reg = <0x2 0x0 0x00040000>;
			status = "disabled";

			u-boot-nand@0 {
				/* This location must not be altered  */
				/* 1MB for u-boot Bootloader Image */
				reg = <0x0 0x00100000>;
				read-only;
			};
		}

When booting from nor flash, the status of nor node is enabled and the
status of nand node is disabled in the default dts file, so do not do
anything.

But, when booting from nand flash, need to do some operations:

	o Disable the NOR node by setting status = "disabled";
	o Enable the NAND node by setting status = "okay";

What is this?

=============

This tool is a Python script which:
- Creates patch directly from your branch
- Cleans them up by removing unwanted tags
- Inserts a cover letter with change lists
- Runs the patches through checkpatch.pl and its own checks
- Optionally emails them out to selected people

It is intended to automate patch creation and make it a less
error-prone process. It is useful for U-Boot and Linux work so far,
since it uses the checkpatch.pl script.

It is configured almost entirely by tags it finds in your commits.
This means that you can work on a number of different branches at
once, and keep the settings with each branch rather than having to
git format-patch, git send-email, etc. with the correct parameters
each time. So for example if you put:

in one of your commits, the series will be sent there.

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.
