sh: sh7785lcr: fix PCI address map for 32-bit mode

2009-04-06T15:55:51+00:00

Fix the problem that cannot work PCI device on 32-bit mode because
influence of the commit 68b42d1b548be1840aff7122fdebeb804daf0fa3
("sh: sh7785lcr: Map whole PCI address space."). So this patch was
implement like a 29-bit mode, map whole physical address space of
DDR-SDRAM.

sh: sh7785lcr: Map whole PCI address space.

2009-04-04T15:50:52+00:00

PCI still doesn't work on sh7785lcr 29bit 256M map mode.

On SH7785, PCI -> SHwy address translation is not base+offset but
somewhat like base|offset (See HW Manual (rej09b0261) Fig. 13.11).
So, you can't export CS2,3,4,5 by 256M at CS2 (results CS0,1,2,3
exported, I guess).  There are two candidates.

a) 128M@CS2 + 128M@CS4
b) 512M@CS0

Attached patch is B. It maps 512M Byte at 0 independently of memory
size. It results CS0 to CS6 and perhaps some more being accessible
from PCI.

Tested on
7785lcr 29bit 128M map
7785lcr 29bit 256M map
(NOT tested on 32bit)

sh: Fix up number of on-chip DMA channels on SH7091.

2009-04-04T15:40:22+00:00

This accidentally regressed when the multi-IRQ changes went in,
switching SH7091 from 4 to 6 channels. Add SH7091 back in to the
4-channel dependency list.

sh: dma: Make PVR2 DMA configurable.

2009-03-17T00:30:36+00:00

With arch/sh/drivers/dma/ always being built, the Dreamcast DMA engines
are being unconditionally built in, regardless of whether the DMA API is
enabled or not. This is a regression from previous behaviour, but there
is not much advantage in building them all in unconditionally regardless.
Add a new config option to make it optional, and update the only user of
it to reflect that.

sh: Move IRQ multi definition of DMAC to defconfig

2009-03-16T11:14:25+00:00

When SuperH CPU has IRQ multi of DMAC, SH_DMA_IRQ_MULTI becomes enable.
The following CPU's are Multi IRQ of DMAC now.
 - SH775X and SH7091
 - SH776X
 - SH7780
 - SH7785

If SH_DMA_IRQ_MULTI becomes enable, dma-sh api driver is optimized
for Multi IRQ.

sh: Disable get_dma_error_irq for non-SH4 targets.

2009-03-16T10:49:01+00:00

dma-sh's get_dma_error_irq() is only used by SH4, as the SH3
doesn't have the DMA Error interrupt.

Disable it out for non-SH4 builds.

sh: dma-sh updates for multi IRQ and new SH-4A CPUs.

2009-03-10T08:26:49+00:00

This adds DMA support for newer SH-4A CPUs, particularly SH7763/64/80/85.

This also enables multi IRQ support for platforms that have multiple
vectors bound to the same IRQ source.
