Subject: [RFC 1/2] kirkwood: add support for booting via oftree probe
Date: Sun, 22 Jun 2014 22:34:14 +0200 [thread overview]
Message-ID: <1403469255-9019-1-git-send-email-alex.aring@gmail.com> (raw)
This patch initialize memory only if we boot a kirkwood arch with
device-tree probing. Otherwise some devices like timer or uart will
be probed twice.
Signed-off-by: Alexander Aring <alex.aring@gmail.com>

I don't know if this is right. The guruplug is the other kirkwood platform
but don't have devictree support.
