[U-Boot] [PATCH V2] example/standalone: introduce STANDALONE_LOAD_ADDR

Sat Mar 14 12:13:02 CET 2009
that could be overwrite in following order
ARCH
CPU
SOC
BOARD
via the corresponding config.mk
the value could be exported to the environment to reduce the user mistake
when they try to use example's standalone application

V2:
fix a typo on the comment
and rename EXAMPLE_LOAD_ADRR to STANDALONE_LOAD_ADDR
Best Regards,
J.
