[PATCH 0/3] SRAM map series

[Santosh Shilimkar <santosh.shilimkar@ti.com>]

Currently we map 1 MB section while setting up SRAM on OMAPs.
The actual physcal OCM RAM available on OMAP SOCs is in order
of KBs. On the newer ARMs with speculation, this is dangerous and can
result in untraceable aborts.
On Davinci as well because of section limitation the SRAM is
marked as MT_DEVICE

First patch of this series addresses the section mapping limiaton and
now we can map such memories as page level granularity.

The series is generated against latest manline commit "2d530569730"
and boot tested on OMAP4430SDP, OMAP3430SDP platforms with 
omap_4430sdp_defconfig and multi-omap(omap3_defconfig) builds

Santosh Shilimkar (3):
  ARM: mmu: Setup MT_MEMORY and MT_MEMORY_NONACHED L1 entries
  omap1/2/3/4: map only available SRAM
  davinci: Map sram using MT_MEMORY_NONCACHED instead of MT_DEVICE
