Subject: ARM: arm1176: Define arch_cpu_init() at the SoC level
X-Git-Tag: v2012.10-rc2~66
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=59d63f7d2cad78382574beea01c85cbca96925df;p=oweals%2Fu-boot.git

ARM: arm1176: Define arch_cpu_init() at the SoC level

Commit 86c6326 "ARM: arm1176: enable instruction cache in
arch_cpu_init()" defined arch_cpu_init() in a file that is shared across
all arm1176 SoCs. tnetv107x already implemented this function, which
caused linking to break. Move the new conflicting arch_cpu_init() into
arm1176/bcm2835/init.c so that it doesn't conflict; grep indicates this
function is usually defined at the SoC-level, not the CPU-level, at least
for ARM.
