2008-01-28sh: Add support for SH7763 CPU subtype.Yoshihiro Shimoda5-4/+524
Signed-off-by: Yoshihiro Shimoda <shimoda.yoshihiro@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Add support for SH7721 CPU subtype.Yoshihiro Shimoda6-10/+26

2008-01-28sh: Encode L1/L2 cache shape in auxvt.Paul Mundt2-1/+31
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: Preparation for uncached jumps through PMB.Stuart Menefy3-6/+15
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 Menefy4-57/+23
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.

2008-01-28sh: Provide a 29/32-bit physical hint for bootloaders.Stuart Menefy1-1/+5
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 ].

2008-01-28sh: Add a printk() to warn legacy mem= growers.Stuart Menefy1-0/+11
mem= can't be used to grow the size of kernel memory, so provide a warning to that effect. Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-01-28sh: Add SH7263 CPU support.Paul Mundt5-4/+48
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>

2008-01-28sh: Merge sh and sh64 module.c.Paul Mundt1-13/+49
This is trivial, in that they're both effectively the same for the base relocations anyways. SH-5 doesn't need the unaligned bits, and has a few extra relocations, which are never hit on non-SH5 parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
