sh: Fix SH-4 DMAC CHCR masking.

2007-10-07T20:19:36+00:00

This patch fixes the DMA cascade by masking the correct bits.

Tested and working with Dreamcast PVR2 DMA. With this patch applied
the existing mainline code in arch/sh/drivers/dma/dma-sh.c works,
whereas before I was patching that to get round this problem.

sh: Fix up extended mode TLB for SH-X2+ cores.

2007-09-21T02:57:55+00:00

The extended mode TLB requires both 64-bit PTEs and a 64-bit pgprot,
correspondingly, the PGD also has to be 64-bits, so fix that up.

The kernel and user permission bits really are decoupled in early
cuts of the silicon, which means that we also have to set corresponding
kernel permissions on user pages or we end up with user pages that the
kernel simply can't touch (!).

Finally, with those things corrected, really enable MMUCR.ME and
correct the PTEA value (this simply needs to be the upper 32-bits
of the PTE, with the size and protection bit encoding).

sh: remove support for sh73180 and solution engine 73180

2007-07-25T01:49:21+00:00

This patch removes old dead code:
- kill off sh73180 cpu support
- get rid of broken solution engine 73180 board support

sh: Preliminary support for the SH-X3 CPU.

2007-06-20T09:27:10+00:00

This adds basic support for UP SH-X3.

sh: trivial build cleanups.

2007-05-31T04:46:21+00:00

Several errors were spotted during building for custom config (SMP
included). Although SMP still does not compile (no ipi and
__smp_call_function) and does not work, this looks a bit cleaner.
Some other errors obtained via gcc-4.1.0 build.

sh: dma: use __maybe_unused

2007-05-09T19:30:57+00:00

There is no such thing as labeling a variable as __attribute__((used)).  Since
ts_shift is not referenced in inline assembly, we assume that we're simply
suppressing a warning here if the variable is declared but unreferenced.

sh: Add SH7785 Highlander board support (R7785RP).

2007-05-07T02:10:53+00:00

This adds preliminary support for the SH7785-based Highlander board.
Some of the Highlander support code is reordered so that most of it
can be reused directly.

This also plugs in missing SH7785 checks in the places that need it,
as this is the first board to support the CPU.

sh: Revert lazy dcache writeback changes.

2007-03-05T10:46:47+00:00

These ended up causing too many problems on older parts,
revert for now..

sh: Missing flush_dcache_all() proto in cacheflush.h.

2007-02-13T02:09:15+00:00

Some boards need this, so provide a definition.
