Subject: ARM: omap: Remove unused arch/arm/cpu/armv7/omap3/mem.c
X-Git-Tag: v2014.10-rc1~38^2~11^2~23
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=6d3bbdb0e718aba1e63086d27392f36c81f338fe;p=oweals%2Fu-boot.git

ARM: omap: Remove unused arch/arm/cpu/armv7/omap3/mem.c

These functions have been merged into the common GPMC init code
with this commit a0a37183 (ARM: omap: merge GPMC initialization code
for all platform). The file is not compiled any more. So remove it
as well.
