* Rewrite for handling most xilinx platforms
* Add helper functions for configuring the target board
* User must add in local.conf:
TARGET_ARCH = "powerpc" | "microblaze"
XILINX_BOARD = "ml401" | "ml403" | "ml410" | "ml507" | "ml510"
whit this varibales u-boot and the linux kernel gets configured
for a selected board.
