Subject: [PATCH 0/5] introduce unaligned access under a Kconfig option
Date: Tue, 29 Jan 2019 13:49:37 +0300 [thread overview]
Message-ID: <20190129104942.31705-1-Eugeniy.Paltsev@synopsys.com> (raw)
As of today we enable unaligned access unconditionally on ARCv2.
Lets move it under Kconfig option and use it actively in SW if it is
enabled.
While I'm at it fix and optimise ARCv2 memcpy implementaion.
Eugeniy Paltsev (5):
ARCv2: lib: memcpy: fix doing prefetchw outside of buffer
ARCv2: introduce unaligned access under a Kconfig option
ARCv2: Enable unaligned access in early ASM code
ARCv2: use unaligned access in SW
ARCv2: LIB: MEMCPY: fixed and optimised routine
