Subject: [PATCH 0/4] arm/cpu/lowlevel cleanups
Date: Thu, 11 Dec 2014 10:15:23 +0100	[thread overview]
Message-ID: <1418289327-28310-1-git-send-email-u.kleine-koenig@pengutronix.de> (raw)

Hello,

similar to how the d-cache is cleaned before enabling the same should be
done for the i-cache.

I'd not consider this series as urgent because of patch 4. I created
this series because there was a problem that could have happend because
of stale entries in the i-cache, but this proved to be wrong. Still for
correctness sake the patch should applied.

The other three patches are just minor cleanups that I did on the way to
create patch 4.

Uwe Kleine-König (4):
  arm/cpu/lowlevel: add and fix comments for CPSR and SCTLR accesses
  arm/cpu/lowlevel: Use coprocessor instruction for ARMv7, too
  arm/cpu/lowlevel: Don't save the return address in another register
  arm/cpu/lowlevel: invalidate i-cache before enabling
