Subject: [PATCH 2/2] [hack] sh: disable initialisation of SDRAM
Date: Fri, 26 Nov 2010 23:05:57 +0000	[thread overview]
Message-ID: <1290812757-20571-3-git-send-email-horms@verge.net.au> (raw)
In-Reply-To: <1290812757-20571-1-git-send-email-horms@verge.net.au>

This disables SDRAM initialisation in very early boot
to allow a zImage to be booted from uboot.

This change applies on top of "ARM: mach-shmobile: Add zboot support for
SuperH Mobile ARM".
