The ST40 stuff in-tree hasn't built for some time, and hasn't been
updated for over 3 years. ST maintains their own out-of-tree changes
and rebases occasionally, and that's ultimately where all of the ST40
users go anyways.

In order for the ST40 code to be brought up to date most of the stuff
removed in this changeset would have to be rewritten anyways, so there's
very little benefit in keeping the remnants around either.

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes.  Originally it was basically the raw
MIPS low level cache API exported to the entire world.  The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync.  So
remove it rsp.  turn the surviving bits back into an arch private API, as
discussed on linux-arch.

This patch converts the board specific interrupt code for r2d to make
use of intc. While at it we improve the Kconfig to avoid confusion.

- Two sets of interrupt tables exist - one for R2D-1 and one for R2D-PLUS.
- R2D-1 and R2D-PLUS use the same irq constants.
- R2D-1 has AX88796 support, R2D-PLUS does not hook up that IRQ.
- R2D-PLUS has KEY support, R2D-1 does not hook up that IRQ.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 100.
- The machvec demux function converts from irlm IRQ 0-14 to IRQ 100++.

Tested on R2D-1 and R2D-PLUS boards.

Version 2 adds CONFIG_RTS7751R2D_1 and CONFIG_RTS7751R2D_PLUS together
with intc structured as __initdata.

The current SH DMA API is somewhat broken, not correctly matching
virtual channel to the correct SH DMAC. This wasn't noticeable when
using g2 DMA for the sound driver - one channel 0 is as good as any
other! - but caused the pvr2 driver to fail.

This patch fixes the pvr2 problem and consequently fixes the sound
driver to ensure it continues to function.

This patch updates the r2d board support in a few ways:

- CPU_SUBTYPE_SH7751R is selected in the defconfig to play well
  with the r2d board Kconfig entry. Without this the defconfig
  results in no board enabled.

- Enable EARLY_PRINTK.
- Enable SH_STANDARD_BIOS
	- this works well for early printk on the r2d board.

- Add "earlyprink=bios" to the cmdline for early serial port
  output by default.

- CONFIG_SUBTYPE_SH7751R support is added to the sh-specific
  pci makefile.

transfers from main memory to Audio units and USB shared memory.
It has 3 IRQ lines which generate 10 events, which have to be masked
unmasked and acked in a single 32bit register. It works independently

When a SH7751R system includes a card that has wide range space
like a graphics card, the pci-pci bridge controller can't set the
correct address range.

For example, when *lower_limit is 0xfd000000 and bar_size is
0x4000000, in the following code at arch/sh/drivers/pci/pci-auto.c,
0x0 is set in bar_value.

pciauto_setup_bars()
{
...
                bar_value = ((*lower_limit - 1) & ~(bar_size - 1)) + bar_size;
...
                *lower_limit = bar_value + bar_size;
}

As a result, 0x4000000 is set in *lower_limit, but this value is wrong.

The following patch avoids this problem by checking the range of the
value and refusing to update the BAR if the calculated value ends up
being bogus.

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.
