2008-01-28sh: intc - remove default interrupt priority tablesMagnus Damm
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: Update SE7712 PCLK definition.Andrew Murray
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: Always use CONFIG_HZ for HZ.Paul Mundt
Currently the wdt forces HZ=1000 and sidesteps CONFIG_HZ completely. This is a remnant from when HZ was hardcoded and before CONFIG_HZ was introduced. Additionally, not all of the timers have this requirement these days, so it's also an artificial limitation. Just kill it off and use CONFIG_HZ directly. Reported-by: H.

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: 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.

2008-01-28sh: CCR1->CCR renaming for SH-2 parts.Paul Mundt

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 ].
