[U-Boot] [PATCH v3 00/10] vexpress64 FVP and Juno configuration updates

This patch series updates the default configuration of the vexpress64 FVP and Juno platforms to allow it to work on a variety of setups without modification by the user.

Changes since v1: - dropped the Kconfig changes for CONFIG_SYS_BOOTM_LEN - added CONFIG_SYS_BOOTM_LEN to include/configs/vexpress_aemv8a.h
Changes since v2: - fixed warning in cmd_armflash.c due to missing hunk from patch 07/10: common/cmd_armflash.c:207:4: warning: 'return' with no value, in function returning non-void [-Wreturn-type]

The FVP and Juno settings were identical, but duplicated, so I removed the duplication with this patch.

As config migrates from board config files to Kconfig, when adding CONFIG_SYS_BOOTM_LEN to a platform, I decided to add Kconfig support for CONFIG_SYS_BOOTM_LEN.

vexpress64 kernels are usually over 8 MBytes in length, so setting the max uImage length to 0x4000000 (64 Mbytes) should give us plenty of scope for expansion.
I mostly chose this length to match other board configs that use "(64 << 20)", however, Kconfig doesn't allow arithmetic operations.

I'm sorry about this, it's becoming embarassing: I've dropped the maintainer hunk this time.

Apologies.

2.1.0

Linaro's Juno Android builds requires the androidboot.hardware parameter be set to a know board name.
Non-Android kernels ignore this extra parameter because they don't contain code to parse it.

Add a command to the ARM flash support to check if an image exists or not.
If the image is found, it will return CMD_RET_SUCCESS, else CMD_RET_FAILURE. This allows hush scripts to conditionally load images.
A simple example:
if afs exists ${kernel_name}; then echo found; else echo \ not found; fi

Change the load_image so that it returns success or failure of the command (using CMD_RET_SUCCESS or CMD_RET_FAILURE).
This way, hush scripts can optionally load different files depending upon the system configuration.

Some OS images require an initrd on Juno.
If the file ramdisk.img exists in NOR flash, then we load it and pass the address to the kernel. Otherwise, we pass the "-" parameter as before.

The default Juno firmware has renamed the kernel and device tree filenames to norkern and board.dtb.
Rather than change the default configuration to use the new names, breaking those with the old firmware, attempt to load the existing filename first. If that fails, attempt to load the alternate filename.
I've echo'd that we are loading the alternate file to counter the output from "afs load" when the first load attempt fails. For example, I see this output on my Juno board:

How about future proofing this and add a board.scr image in Juno firmware where a script can be stored (can the image be used by UEFI as well?).
Now that you are adding support for testing if an image is present we can then source the script at boot.scr. That would allow Juno r1 for example to have a different boot script than r0 (smc911x ethernet port was designed as a backup solution until PCIe was functional, so one might not want to use it for booting).
Thoughts?
Best regards, Liviu
I've echo'd that we are loading the alternate file to counter the output from "afs load" when the first load attempt fails. For example, I see this output on my Juno board:

Hi Ryan,

The default Juno firmware has renamed the kernel and device tree filenames to norkern and board.dtb.
Rather than change the default configuration to use the new names, breaking those with the old firmware, attempt to load the existing filename first. If that fails, attempt to load the alternate filename.
How about future proofing this and add a board.scr image in Juno firmware where a script can be stored (can the image be used by UEFI as well?).
Now that you are adding support for testing if an image is present we can then source the script at boot.scr. That would allow Juno r1 for example to have a different boot script than r0 (smc911x ethernet port was designed as a backup solution until PCIe was functional, so one might not want to use it for booting).
Thoughts?
Sounds like a good idea. I'll have a play with it here and see what I can come up with.
Best regards, Liviu

One small step for me ...

This patch changes the default "root=" parameter to "/dev/sda2".
Many linux based distros use /dev/sda1 for their boot partition; this is often not a rootfs that can be used by the "root=" parameter.
Linaro images use /dev/sda1 as a boot partition, although this of a different nature to a distro image. Linaro uses /dev/sda2 for the rootfs partition.
