arm: mvebu: Add option to use UART xmodem protocol via kwboot
This patch enables the use of the kwboot tool, to boot mainline U-Boot
on the Marvell Armada XP/38x SoC's. This is done by returning to the
SoC's BootROM after SPL has initialized the SDRAM. We need to make sure
to not reconfigure the internal register space and MBARs. Otherwise
the BootROM will not be able to continue after SPL jumps back to it.
To use this feature, please don't forget to change the BOOT_FROM line
in your board specfic kwbimage.cfg file this way:
BOOT_FROM uart
Tested on these Marvell eval boards:
DB-MV784MP-GP - Armada XP
DB-88F6820-GP - Armada 38x
