Subject: board/emk/top860/top860.c: Fix GCC 4.6 build warning
X-Git-Tag: v2011.12-rc1~106^2
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f008b17f8c2995996b5d100b71f8851d6f74a136;p=oweals%2Fu-boot.git

board/emk/top860/top860.c: Fix GCC 4.6 build warning

Fix:
top860.c: In function 'initdram':
top860.c:90:11: warning: variable 'j' set but not used
[-Wunused-but-set-variable]

Note: No attempts were made to convert this file completely to using
I/O accessors. This is left as an exercise for the board maintainer.
