Subject: split mpc8xx hooks from cmd_ide.c
X-Git-Tag: v2013.01-rc1~162
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8d1165e11a7aad00a2bbb05f20bacf021f6d1c12;p=kernel%2Fu-boot.git

split mpc8xx hooks from cmd_ide.c

move most of mpc8xx hooks from cmd_ide.c into ide_preinit() and newly created
ide_init_postreset() (invoked after calling ide_reset after ide_preinit),
some cleanup to make checkpatch happy, enable IDE init hooks in configs of
affected boards.
confusingly, these hooks are used by more than just mpc8xx-based boards, and
therefore are placed in arch/ppc/lib/

note: checkpatch still emits warnings about using volatile
