From mboxrd@z Thu Jan 1 00:00:00 1970 From: magnus.damm@gmail.com (Magnus Damm) Date: Wed, 05 Jun 2013 16:55:22 +0900 Subject: [PATCH 01/02] ARM: shmobile: Let romImage rely on default ATAGS In-Reply-To: <20130605075514.17653.77135.sendpatchset@w520> References: <20130605075514.17653.77135.sendpatchset@w520> Message-ID: <20130605075522.17653.20769.sendpatchset@w520> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Magnus Damm 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.
