Subject: [PATCH 00/35 v2] m68k: ColdFire MMU support
Date: Fri, 25 Nov 2011 13:40:45 +1000 [thread overview]
Message-ID: <1322192480-22822-1-git-send-email-gerg@snapgear.com> (raw)
Hi All,
This is version 2 of a patch set that adds support for running the V4e
ColdFire cores with their MMU enabled. A bit of cleanup and some fixes over
the first version. In particular the following changes:
. rebased onto 3.2-rc3
. fixed FPU support
. fixed running with shared libraries
. fixed running at non-0 based RAM (thanks to Alexander Stein)
. many random small cleanups
. spelling and comment fixes
This patch set is based on 3.2-rc3 with all the recent patches I have sent
here applied first. It is available as a git tree for easier testing, just
pull this tree, with the cfmmu branch:
git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu.git cfmmu
Some of the code in this set is taken from Freescales 2.6.25 kernel support
of MMU ColdFire.
Specifically I am testing this on a ColdFire 5475 (on a FireBee board).
I have test compiled and run this patch set on ARAnyM as well, I didn't have
any problems there. Also test compiled and run on MMU-less ColdFire.
Geert, any patches that changed in any significant way I dropped your
"Acked-by".
Regards
Greg
