* sh: add spi header and r2d platform data V3Magnus Damm2008-01-281-0/+13
| | | | | | | | | | | | This patch adds the header file asm/spi.h and board specific code for the r2d board. The header file contains a structure that should be used to point out a single spi bus. The board specific code for r2d is updated with such a structure for the new spi_sh_sci driver. The structure contains a chip select callback plus information about the R9701 rtc chip which is attached to the spi bus.

* sh: update r7780rp interrupt codeMagnus Damm2008-01-281-19/+0
| | | | | | | | | | | | | | | | | | This patch updates the board specific irq code for r7780rp. The new code is very similar to the other highlander implementations, with the exception that the r7780rp handles pci interrupts using IRL. To simplify the pci code and use the same interrupt numbers as r7780mp and r7785rp we hook in to the cpu specific pci vectors. The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access. As a workaround this patch removes the CF and the AX88796 from the platform datain case of r7780rp. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: remove consistent alloc stuff from the machine vectorMagnus Damm2008-01-281-3/+0
| | | | | | | | | | | Now with the voyagergx cruft gone and the dreamcast using declared coherent memory for pci there are no users of the consistent alloc and free functions pointers in the machine vector. So this little patch simply removes these function pointers from the macvec. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: declared coherent memory support V2Magnus Damm2008-01-281-36/+20
| | | | | | | | | | | | This patch adds declared coherent memory support to the sh architecture. All functions are based on the x86 implementation. Header files are adjusted to use the new functions instead of the former consistent_alloc() code. This version includes the few changes what were included in the fix patch together with modifications based on feedback from Paul.

| | | | | | | | | 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 Damm2008-01-281-11/+1
| | | | | | | | | | | | | 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 Mundt2008-01-281-5/+1
| | | | | | | | | | | 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.

* sh: get_user fixes and nommu consolidation.Stuart Menefy2008-01-281-155/+98
| | | | | | | | | | | | | | | | 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 Menefy2008-01-285-20/+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.
