All the verification for this defconfig was with USB boot for the first
stage (ULO). UART cannot be tested with our DRA7xx EVMs as you pointed
out and to test on AM57xx special scrips need to be used as the ROM UART
loading protocol is not standard. UART loading of the second stage is
possible after loading the first stage using some other boot media.

On HS, both USB and UART are special in their load address requirements,
this patch set fixes that. The UART support on HS cannot work with the
old defconfig.
