Subject: [PATCH] POWERPC 8xx: bump up initial memory limit for 8xx
Date: Tue, 17 Jul 2007 05:17:23 +0400 [thread overview]
Message-ID: <20070717011723.23549.44672.stgit@localhost.localdomain> (raw)
From: John Traill <john.traill@freescale.com>
The 8xx can only support a max of 8M during early boot ( it seems a lot of
8xx boards only have 8M so the bug was never triggered ). The following
change makes it able to run with 128M.
