sh: Move arch_get_unmapped_area() in to arch/sh/mm/mmap.c.

2008-12-22T09:42:49+00:00

Now that arch/sh/mm/mmap.c exists, move arch_get_unmapped_area() there.
Follows the ARM change.

sh: Encode L1/L2 cache shape in auxvt.

2008-01-28T04:18:59+00:00

This adds in the L1I/L1D/L2 cache shape support to their respective
entries in the ELF auxvt, based on the Alpha implementation. We use
this on the userspace libc side for calculating a tightly packed
SHMLBA amongst other things.

sh: Preparation for uncached jumps through PMB.

2008-01-28T04:18:59+00:00

Presently most of the 29-bit physical parts do P1/P2 segmentation
with a 1:1 cached/uncached mapping, jumping between the two to
control the caching behaviour. This provides the basic infrastructure
to maintain this behaviour on 32-bit physical parts that don't map
P1/P2 at all, using a shiny new linker section and corresponding
fixmap entry.

sh: Bring SMP support back from the dead.

2007-09-21T09:32:32+00:00

There was a very preliminary bunch of SMP code scattered around for the
SH7604 microcontrollers from way back when, and it has mostly suffered
bitrot since then. With the tree already having been slowly getting
prepped for SMP, this plugs in most of the remaining platform-independent
bits.

sh: Support explicit L1 cache disabling.

2007-09-21T02:57:46+00:00

This reworks the cache mode configuration in Kconfig, and allows for
explicit selection of write-back/write-through/off configurations.
All of the cache flushing routines are optimized away for the off
case.

sh: Tidy up dependencies for SH-2 build.

2007-06-11T06:32:07+00:00

SH-2 can presently get in to some pretty bogus states, so
we tidy up the dependencies a bit and get it all building
again.

This gets us a bit closer to a functional allyesconfig
and allmodconfig, though there are still a few things to
fix up.

sh: speculative execution support for SH7780.

2007-05-07T02:10:51+00:00

SH7780 has a speculative execution mode where it can speculatively
perform an instruction fetch for subroutine returns, this allows it
to be enabled. There are some various pitfalls associated with this
mode, so it's left as depending on CONFIG_EXPERIMENTAL and not
enabled by default.
