2008-01-28sh: intc - remove default interrupt priority tablesMagnus Damm18-144/+41
This patch removes interrupt priority tables from the intc code. Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Correct pte size mismatch for X2 TLB.Paul Mundt1-1/+1

2008-01-28sh: Update SE7712 PCLK definition.Andrew Murray1-1/+1
This patch provides a correct value for CONFIG_SH_PCLK_FREQ for the SH7712 solution engine when used with the board's default factory settings. This results in the board running at its maximum CPU clock rate (200 MHz). Signed-off-by: Andrew Murray <amurray@mpc-data.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

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: Fix up uImage target entry point.Thomas Betker1-4/+15
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: Populate swapper_pg_dir with fixmap range.Stuart Menefy1-0/+36

2008-01-28sh: Preparation for uncached jumps through PMB.Stuart Menefy9-36/+61
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 Menefy5-58/+34
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 ].
