[ARM] 3269/1: Add ARMv6 MT_NONSHARED_DEVICE mem_types[] index
Patch from George G. Davis This Freescale Semiconductor, Inc. contributed patch adds mem_types[] support for ARMv6 non-shared device memory region attributes. This implementation provides support for only first level section mapped non-shared devices. Second level non-shared device mappings are not yet supported. Signed-off-by: George G. Davis <gdavis@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
