Subject: [PATCH 1/2] mpc85xx: remove local bus initialisation
Date: Wed, 31 Jul 2013 10:43:14 +0100	[thread overview]
Message-ID: <1375263795-5348-2-git-send-email-renaud.barbier@ge.com> (raw)
In-Reply-To: <1375263795-5348-1-git-send-email-renaud.barbier@ge.com>

The early initialisation of chip select 0 (boot flash) is removed
from cpu initialisation. This removes the dependency on board
base address definition.

Consequently, cpu_init_f is not called in the start-up code but
added to the init call list as cpu_init_r. Also the file
arch/ppc/mach-mpc85xx/fsl_lbc.c is deleted.
