* sh: r7785rp: Hook up the rest of the HL7785 FPGA IRQ vectors.Paul Mundt2008-01-27
| | | | Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: remove voyagergxMagnus Damm2008-01-27
| | | | | | | | | This patch removes redundant irq handling code together with unused consistent alloc code. R2D uart setup code is changed to use sm501-regs.h and unused header files are removed. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - remove default interrupt priority tablesMagnus Damm2008-01-27
| | | | | | | | | | | | | 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>

* sh: Always use CONFIG_HZ for HZ.Paul Mundt2008-01-27
| | | | | | | | | | | 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.

| | | | | | | | | 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>

* sh: get_user fixes and nommu consolidation.Stuart Menefy2008-01-27
| | | | | | | | | | | | | | | | 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.

* sh: Preparation for uncached jumps through PMB.Stuart Menefy2008-01-27
| | | | | | | | | | | | 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.

* sh: GUSA atomic rollback support.Stuart Menefy2008-01-27
| | | | | | | | | | 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.

* rtc: rtc-sh: Split out the CPU defs to asm/cpu/.Paul Mundt2008-01-27
| | | | | | | | | | | 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>
* sh: CCR1->CCR renaming for SH-2 parts.Paul Mundt2008-01-27
| | | | | | | | | | | | | | | | | | | | | 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.
