[U-Boot] [PATCH v2 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
This patch fixes a couple of checkpatch warnings on the vexpress64 config.

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

vexpress64 kernels are usually over 8 MBytes in length, so setting the max uImage length to 64 Mbytes should give us plenty of scope for expansion.
I mostly chose this length to match other board configs that use "(64 << 20)".

Create an additional FVP configuration to boot images pre-loaded into DRAM.
Sometimes it's preferential to boot the model by loading the files directly into DRAM via model parameters, rather than using SemiHosting.
An example of model parmaters that are used to pre-load the files into DRAM: --data cluster0.cpu0=Image@0x80080000 \ --data cluster0.cpu0=fvp-base-gicv2-psci.dtb@0x83000000 \ --data cluster0.cpu0=uInitrd@0x84000000

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.
A simple example:
if afs load ${kernel_name} ${kernel_addr}; then echo loaded; else echo \ not loaded; fi

I somehow managed to drop a hunk from this patch, leaving a return without a value. I'll issue a v3 of the series to correct it.

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:
image "Image" not found in flash Loading norkern instead of Image loaded region 0 from 08500000 to 80000000, 00AB6318 bytes image "juno" not found in flash Loading board.dtb instead of juno loaded region 0 from 0A000000 to 83000000, 00003188 bytes

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.
