Bug Description

U-Boot for Versatile Express doesn't try and boot from the boot script (boot.scr) in the boot partition, this should be fixed.
Also, even when running this script by hand booting fails. This may be because linaro-media-create uses double quotes (") in the script and our U-Boot versions doesn't understand this?

For the record, to manually configure U-Boot to boot from MMC, the following environment variables can be used:

setenv bootargs 'root=/dev/mmcblk0p2 ro console=ttyAMA0,38400n8 mem=1024M ip=dhcp clcd=xvga rootwait mmci.fmax=4000000'
setenv bootload 'mmc rescan; fatload mmc 0:1 0x60000000 uImage; fatload mmc 0:1 0x62000000 uInitrd'
setenv bootcmd 'run bootload; bootm 0x60000000 0x62000000'
run bootcmd

... and if you're booting the A5 platform, you should change the address prefixes from 0x6.... to 0x8....:

Eg:

setenv bootargs 'root=/dev/mmcblk0p2 ro console=ttyAMA0,38400n8 mem=1024M ip=dhcp clcd=xvga rootwait mmci.fmax=4000000'
setenv bootload 'mmc rescan; fatload mmc 0:1 0x80000000 uImage; fatload mmc 0:1 0x82000000 uInitrd'
setenv bootcmd 'run bootload; bootm 0x80000000 0x82000000'
run bootcmd

Try building u-boot with CONFIG_SYS_HUSH_PARSER to get proper support for our boot script syntax

Concerning load address, you could have a separate board+config for a5 or you could build the same board twice under different names, see how efikasb/efikamx does this for instance. If there's a way to detect this at runtime, that would be ideal though!

This isn't actually released until it gets merged into Linaro's U-Boot

Except that at the moment the hwpack doesn't contain UEFI, so if Linaro U-Boot doesn't work, then the Ubuntu image won't have a working bootloader. And even if we move over to UEFI, that doesn't seem to work reliably yet..

Android builds U-Boot out of my personal branch which is a fork and hacked up version I made some time ago, and that does work for all CoreTiles. So I guess we can point people at that if they want a working bootloader.

This fix isn't in Linaro's U-Boot or in mainline and the ARM Landing Team don't support U-Boot, so this bug is actually "won't fix'
