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

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.

Some boards need this, so provide a definition.

sh: SH-DMAC compile fixes

2007-02-13T01:54:45+00:00

This patch does the following:
- remove the make_ipr_irq stuff from dma-sh.c and replace it
  with a simple channel<->irq mapping table.
- add DMTEx_IRQ constants for sh4 cpus
- fix sh7751 DMAE irq number

The SH7780 uses the same IRQs for DMA as other SH4 types, so
I put the constants on top of the dma.h file.

Other CPU types need to #define their own DMTEx_IRQ contants
in their appropriate header.

sh: Lazy dcache writeback optimizations.

2007-02-13T01:54:44+00:00

This converts the lazy dcache handling to the model described in
Documentation/cachetlb.txt and drops the ptep_get_and_clear() hacks
used for the aliasing dcaches on SH-4 and SH7705 in 32kB mode. As a
bonus, this slightly cuts down on the cache flushing frequency.

With that and the PTEA handling out of the way, the update_mmu_cache()
implementations can be consolidated, and we no longer have to worry
about which configuration the cache is in for the SH7705 case.

And finally, explicitly disable the lazy writeback on SMP (SH-4A).
