sh: Populate swapper_pg_dir with fixmap range. · 2adb4e10

Stuart Menefy authored Nov 30, 2007

This saves us from having to use kmalloc() for the fixmap entries,
which is needed early for the uncached fixmap.

sh: Preparation for uncached jumps through PMB. · cbaa118e

Stuart Menefy authored Nov 30, 2007

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: GUSA atomic rollback support. · 1efe4ce3

Stuart Menefy authored Nov 30, 2007

This implements kernel-level atomic rollback built on top of gUSA,
as an alternative non-IRQ based atomicity method. This is generally
a faster method for platforms that are lacking the LL/SC pairs that
SH-4A and later use, and is only supportable on legacy cores.

rtc: rtc-sh: Split out the CPU defs to asm/cpu/. · c019fd88

Paul Mundt authored Nov 28, 2007

With all of the different CPU types this was getting a but unwieldly.
Since sh64 is now integrated, we don't have to worry about multiple
architectures caring about the header definitions.

Split out the defs for each asm/cpu/ to make rtc-sh slightly less
visually offensive.

sh: CCR1->CCR renaming for SH-2 parts. · 3ee77029

Paul Mundt authored Nov 28, 2007

Avoid namespace collision with a CCR1 definition. The general
SH code always expects CCR anyways, so there's no point in keeping
the CCR1 naming around.

Fixes up synclink collisions:

sh: Provide a 29/32-bit physical hint for bootloaders. · 7a2eacb7

Stuart Menefy authored Nov 26, 2007

Shoves a magic word in to the empty_zero_page section for the
bootloader to work out whether to start the kernel in 29-bit
or 32-bit mode.

[ Renesas CPUs already take care of the initial PMB mappings entirely
  in hardware and decide on 29-bit/32-bit physical depending on which
  pin powered up the CPU, so this is mostly for ST parts. -- PFM ].

This adds support for the SH7263 (SH-2A) CPU.

This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.
