Subject: [PATCH review for 3.18 08/30] ARM: 8635/1: nommu: allow enabling
 REMAP_VECTORS_TO_RAM

From: Afzal Mohammed <afzal.mohd.ma@...il.com>

[ Upstream commit 8a792e9afbce84a0fdaf213fe42bb97382487094 ]

REMAP_VECTORS_TO_RAM depends on DRAM_BASE, but since DRAM_BASE is a
hex, REMAP_VECTORS_TO_RAM could never get enabled. Also depending on
DRAM_BASE is redundant as whenever REMAP_VECTORS_TO_RAM makes itself
available to Kconfig, DRAM_BASE also is available as the Kconfig
gets sourced on !MMU.
