This implements dynamic probing for the system FPGA. The system reset
controller contains a fixed magic read word in order to identify the
FPGA. This just utilizes a simple loop that scans across all of the fixed
physical areas (area 0 through area 6) to locate the FPGA.

The FPGA also contains register information detailing the area mappings
and chip select settings for all of the other blocks, so this needs to be
done before we can set up anything else.

This moves out the FPGA IRQ controller setup code to its own file, in
preparation for switching off of IRL mode and having it provide its own
irq_chip.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This does a bit of refactoring of the FPGA management code. The primary
FPGA initialization is moved out to its own file in preparation for
implementing some of the more complex capabilities, a complete set of
register definitions is provided, and all of the existing users in the
board code are moved over to use the new interface instead of setting up
overlapping mappings. This also corrects the FPGA size, which previously
was chomped off at the SDIF control register.

urquell happens to use the same mode pins and EXTAL configuration as
SDK7786, so just copy it over.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This uses the mode pins exposed through the FPGA to work out whether
we're driven from EXTAL or not and does the appropriate setup and
propagation through the clock framework.

This will also -EINVAL out for anyone adding in their own oscillators,
forcing proper configuration with the clock framework instead of
proceeding on with bogus clock values.

This kills off the ancient p3_ioremap(), converting over to the more
generic ioremap_prot() instead.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Presently 'flags' gets passed around a lot between the various ioremap
helpers and implementations, which is only 32-bits. In the X2TLB case
we use 64-bit pgprots which presently results in the upper 32bits being
chopped off (which handily include our read/write/exec permissions).

As such, we convert everything internally to using pgprot_t directly and
simply convert over with pgprot_val() where needed. With this in place,
transparent fixmap utilization for early ioremap works as expected.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

We need to write to the DRAM config register very early and at such an
early stage ioremap() is not available. So use ioremap_fixed() to map
the register.

The reason that we are avoiding using the legacy P2 mapping is that
there will come a day when the legacy P2 mappings no longer exist.

Previously this was only built in for Urquell boards, but the same
approach can be used on SDK7786 now that the mode pin reading is
supported, so make it generic to SH7786.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This wires up the mode pins support on the SDK7786. The pins are
standard SH7786 pins, and all are fixed in software. Needed for the
clock framework, PCIe, and so forth.

This patch adds MSIOF and mmc_spi platform data for
the CN11 port on the SuperH Ecovec24 board. No card
detect interrupt is available so the MMC code is
configured to poll. The WP signal is implemented
together with CD and power control. The board only
supports 3.3V power.

The platform data is wrapped in SDHI #ifdefs to
allow both the SDHI and the MSIOF to coexist. Only
one configuration is allowed at a time. The pin
routing is selected by a dip switch but we can
unfortunately not detect this setting at run time.

This is a port of the sound/oss/sh_dac_audio.c driver.

to one of its channels, found in several ancient HP machines.
For interrupts it uses a high-resolution timer (hrtimer).
Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx).

Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver
would be obsolete soon, and it could be removed.
