Subject: ARM: Support unaligned memory access.
X-Git-Tag: stable_2012_02_02~841
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dee8f3d50014ae0e300269867d7dbca5fa4759e5;p=gem5.git

ARM: Support unaligned memory access.

Without this flag set, page-crossing requests were not split into two mem
request.

Depending on the alignment bit in the SCTLR, misaligned access could
raise a fault. However it seems unnecessary to implement that.
