X-Git-Tag: v2014.07-rc2~2^2~2^2~5
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=66e6715c5ffe817c70485020508c7b9ec47227b7;p=oweals%2Fu-boot.git

zynq: treat ps7_init.c/h as external files to ignore them

ps7_init.c and ps7_init.h are supposed to be exported by hw project
and copied to board/xilinx/zynq/ directory.

We want them to be ignored by git.
So what we should do is to always treat them as external files
rather than replacing ps7_init.c

This commit does:

 - Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c
   and delete board/xilinx/zynq/ps7_init.c

 - Compile board/xilinx/zynq/ps7_init.c only when it exists

 - Add .gitignore to ignore ps7_init.c/h
