[U-Boot] BUG_ON() uses macro unlikely(), which isn't defined

[Matthias Kaehlcke <matthias@kaehlcke.net>]

include/common.h defines the BUG_ON macro:

#define BUG_ON(condition) do { if (unlikely((condition)!=0)) BUG(); }
while(0)

this macro isn't defined in common.h or its includes

i'd submit a patch to fix this, but i wonder what kind of fix is
preferred:

a) eliminate the use of 'unlikely' in BUG_ON
b) define likely() and unlikely() in common.h
c) define likely() and unlikely() elsewhere
d) ?

best regards
