2008-01-28sh: Encode L1/L2 cache shape in auxvt.Paul Mundt
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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-01-28sh: Fix up uImage target entry point.Thomas Betker
This patch changes the uImage target so that it generates a wrapped compressed vmlinux, rather than a wrapped zImage. The previous version matched the ARM, this version matches the PPC. However I would question how useful a self decompressing image is with a boot loader which does decompression, so I think this is more useful. I also feel it matches the descrition in the help text ("Compressed kernel image") better.

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: Populate swapper_pg_dir with fixmap range.Stuart Menefy
This saves us from having to use kmalloc() for the fixmap entries, which is needed early for the uncached fixmap. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

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: Provide a 29/32-bit physical hint for bootloaders.Stuart Menefy
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 ].
