Subject: Fix warnings while compiling net/net.c for MPC8610HPCD board
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=33a4a70d48d622cc4950c60a84fec23b9421f23e;p=u-boot.git

Fix warnings while compiling net/net.c for MPC8610HPCD board

MPC8610HPCD board adds -O2 gcc option to PLATFORM_CPPFLAGS
causing overriding default -Os option. New gcc (ver. 4.2.2)
produces warnings while compiling net/net.c file with -O2
option. The patch is an attempt to fix this.
