Subject: [PATCH 01/02] ARM: shmobile: Let romImage rely on default ATAGS
Date: Wed, 05 Jun 2013 07:55:22 +0000 [thread overview]
Message-ID: <20130605075522.17653.20769.sendpatchset@w520> (raw)
In-Reply-To: <20130605075514.17653.77135.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Remove the ATAGS data structure from head-shmobile.S
since a default ATAGS is already provided by the code
in arch/arm/kernel/atags_parser.c. Passing a NULL as
ATAGS is valid. For actual hardware specific setup
the fixup callback in the board code may be used.
