5d9df8eeac sh: Fix SH-4 DMAC CHCR masking.
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.

d16aaffa75 sh: dma: use __maybe_unused
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.

9f8a5e3a44 sh: SH-DMAC compile fixes
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.

0d831770b1 [PATCH] sh: DMA updates
This extends the current SH DMA API somewhat to support a proper virtual
channel abstraction, and also works to represent this through the driver model
by giving each DMAC its own platform device.

There's also a few other minor changes to support a few new CPU subtypes, and
make TEI generation for the SH DMAC configurable.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
