Subject: common: add a prototype for mach_cpu_init()
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-favicon.png?a=commitdiff_plain;h=dafa84d27c5f9d160b431665e09697bd392daca9;p=u-boot.git

common: add a prototype for mach_cpu_init()

Add a new file init.h with the prototype for arch_cpu_init
Add a prototype for mach_cpu_init() to avoid a warning:
no previous prototype for ‘mach_cpu_init’

It is a first step to move all the functions prototype
used during U-Boot initialization (board_f.c / board_r.c)
from common.h to init.h
