2008-01-28sh: Support denormalization on SH-4 FPU.Stuart Menefy
Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: get_user fixes and nommu consolidation.Stuart Menefy
When a get_user(to, from++) is called the pointer increment is performed after its first usage, in the specific after the __add_ok invokation. This causes a wrong get_user return value, putting a wrong character in the destination variable. This patch solves the problem using a new temporary pointer. Additionally this reworks the use of the register banks, allowing for consolidation between the MMU and nommu implementations.

2008-01-28sh: Preparation for uncached jumps through PMB.Stuart Menefy
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.

2008-01-28sh: GUSA atomic rollback support.Stuart Menefy
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.

2008-01-28rtc: rtc-sh: Split out the CPU defs to asm/cpu/.Paul Mundt
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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: CCR1->CCR renaming for SH-2 parts.Paul Mundt
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.

2008-01-28sh: Add SH7263 CPU support.Paul Mundt
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. No visibly nasty surprises, yet.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
