[U-Boot] [PATCH 1/7] powerpc/doc: Update the README.srio-pcie-boot-corenet
1. Misalignment will be found in the doc/README.srio-pcie-boot-corenet file when the tabs are set to 8 characters. And the standard for u-boot should be 8 character tabs! So this issue should be amended.
2. Add a NOTE for the ENV parameters of the Slave.

More important than explaining what the patch does is explaining *why*. Why was this change necessary?
Make sure the "why" includes what makes this feature a board feature, as opposed to an SoC feature?

Thanks, I'll updated the commit message. And in addition, why the state of the below patch is superseded? http://patchwork.ozlabs.org/patch/226046/
York has submitted a bunch of patches. I marked yours as superseded to note that I'll take his copy. There are others like that, but I'm holding off on deciding which copy to take until I can review them.

Yes, I have known those patches about this feature in York's list, and pointed out to York and you. I transferred that mail to you, please find it.
In addition, my patches about this feature have some updates compared with York's list, so please apply my patches for this feature, thanks!
And I have sent the patches for version 2 based on your comments.
Thanks a lot!

B4860QDS can support the feature of Boot from SRIO/PCIE, and the macro "CONFIG_SRIO_PCIE_BOOT_MASTER" will enable the master module of this feature when building the u-boot image.
You can get some description about this macro in README file, and for more information about the feature of Boot from SRIO/PCIE, please refer to the document doc/README.srio-pcie-boot-corenet.

When a b4860qds board boots from SRIO or PCIE, it needs to finish these processes: 1. Set all the cores in holdoff status. 2. Set the boot location to one PCIE or SRIO interface by RCW. 3. Set a specific TLB entry for the boot process. 4. Set a LAW entry with the TargetID of one PCIE or SRIO for the boot. 5. Set a specific TLB entry in order to fetch ucode and ENV from master. 6. Set a LAW entry with the TargetID one of the PCIE ports for ucode and ENV. 7. Slave's u-boot image should be generated specifically by make xxxx_SRIO_PCIE_BOOT_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.
For more information about the feature of Boot from SRIO/PCIE, please refer to the document doc/README.srio-pcie-boot-corenet.

T4 can support the feature of Boot from SRIO/PCIE, and the macro "CONFIG_SRIO_PCIE_BOOT_MASTER" will enable the master module of this feature when building the u-boot image.
You can get some description about this macro in README file, and for more information about the feature of Boot from SRIO/PCIE, please refer to the document doc/README.srio-pcie-boot-corenet.

When a T4 board boots from SRIO or PCIE, it needs to finish these processes: 1. Set all the cores in holdoff status. 2. Set the boot location to one PCIE or SRIO interface by RCW. 3. Set a specific TLB entry for the boot process. 4. Set a LAW entry with the TargetID of one PCIE or SRIO for the boot. 5. Set a specific TLB entry in order to fetch ucode and ENV from master. 6. Set a LAW entry with the TargetID one of the PCIE ports for ucode and ENV. 7. Slave's u-boot image should be generated specifically by make xxxx_SRIO_PCIE_BOOT_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.
For more information about the feature of Boot from SRIO/PCIE, please refer to the document doc/README.srio-pcie-boot-corenet.
