Hello,
I have tested v2015.04-rc3 and have stumbled over a problem with the distro_bootcmd framework when trying to boot from a specific device at the u-boot command prompt by using "run <device>_boot". Autobooting without user interruption of the boot process works fine:

Interrupting the boot sequence and then manually executing e.g. "run usb_boot" results in a "** Bad device specification usb devplist **" error message:
sunxi# run usb_boot
USB device 0: Vendor: Intenso Rev: Prod: Rainbow Type: Removable Hard Disk Capacity: 7620.0 MB = 7.4 GB (15605760 x 512) ** Bad device specification usb devplist ** sunxi#
The reason for this is that in this constellation ${devnum} is undefined, which leads to a failure of the "part list ${devtype} ${devnum} devplist" command in ${scan_dev_for_boot_part}. Older versions of u-boot did not use the part list command, so this problem did not occur there. Using "run bootcmd_usb0" instead of "run usb_boot" works, but my understanding (which may of course be wrong) was that the user is expected to use "run <device>_boot" for booting from a specific device at the u-boot command prompt, and that has worked without problems in previous u-boot versions.
Hello,
as my original email appears to have fallen through the cracks, I'd like to ask again whether using "run <device>_boot" is "officially" expected to work or not. If it is not, what is the officially supported way for a user to boot from a certain device at the u-boot prompt? Should people use "setenv boot_targets foo; run bootcmd" instead?
Can you git bisect down to the problem commit and then we can poke the authors and other folks with a strong opinion on the distro bootcmd bits? Thanks again!
