From 2a58009599ff0d2bdbe7e3a9a11a0d838868634d Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 5 Jun 2013 07:55:22 +0000 Subject: ARM: shmobile: Let romImage rely on default ATAGS 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.
