Subject: MIPS: initialize board_init_f() argument to zero.
X-Git-Tag: v2016.03-rc1~14^2~19
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a62790997f9a2e50a168c73e752a471590e8cf4f;p=u-boot

MIPS: initialize board_init_f() argument to zero.

Argument boot_flags of board_init_f() should be set to 0 as
$a0 may be utilized in lowlevel_init() or mips_cache_reset()
or previous stage boot-loader.
