[U-Boot] [RFC PATCH 7/7] Switch am335x_evm.h to use config_distro_defaults and config_distro_bootcmd. Add scriptaddr to DEFAULT_LINUX_BOOT_ENV, as scriptaddr is used for boot scripts in config_distro_bootcmd.

u-boot already supports looking for the (1st) bootable partition.
Giving "<dev>:-" for commands will do that. I think that only works
for DOS partititons, so we need to do something different for GPT
partitions like looking for a certain UUID.

Really? I'd think we'd want this to be a raw partition at least to be
discoverable in some way. What the SOC ROM codes require is probably
all over the map, so we can really only define what we would like to
see.
