Subject: ARM: ebsa110: move platform definitions out of mach/hardware.h

Stop exposing platform definitions to the entire kernel tree, move
them into a private header file instead.

Subject: MFD: mcp-sa11x0: move setup of PPC unit out of mcp-sa11x0.c

Patch taken from af9081ae64 (ARM: sa1100: Refactor mcp-sa11x0 to use
platform resources.) by Jochen Friedrich <jochen@scram.de>, and
consolidated to use a common function.

Move the setup of the PPC unit out of mcp-sa11x0 into the core SA11x0
code, and call it from each platforms initialization file.  This
centralizes the setup of the PPC unit while not polluting the mcp-sa11x0
driver with these details.

Subject: MFD: mcp-sa11x0: convert mcp-sa11x0 to use platform resources

Patch taken from af9081ae64 (ARM: sa1100: Refactor mcp-sa11x0 to use
platform resources.) by Jochen Friedrich <jochen@scram.de>, and fixes
applied.

We can safely do this now that we have sanitized host removal; the
original patch had use-after-free bugs in the removal code.  Not only
that, but there was no checking of the ioremap() return.

The final change over Jochen's patch is that we wrap the base pointer
selection inside the various register indexes, which reduces the
possibility of the wrong register index being used.

Subject: ARM: sa11x0: fix off-by-one resource sizes

Hackkit defined its flash memory resource to be 32M + 1 byte.
Jornada defined the Epson video controller resources to be one byte
larger than they should be, and mis-mapped the SA-1111 companion
chip one byte smaller than it should be.

Fix these.

Subject: ARM: sa11x0: fix sleep entry

Sometimes, we get stuck while trying to enter sleep.  This seems
to occur if we do not have udelay() in the instruction cache. Avoid
this by requesting a short delay prior to modifying the SDRAM timings.

Subject: ARM: sa11x0: fix section mismatch warnings

Neponset calls sa1110_mb_disable() from __devinit code, but
sa1110_mb_disable() is marked __init, and so causes a section
mismatch warning.

As sa1110_mb_enable() and sa1110_mb_disable() need to be callable
from suspend/resume paths as well, they must not be marked __init
or __devinit.

Avoid glitching the GPIO signals during initialization, which can
have undesirable effects.  Ensure that the desired pin state is set
before we change the GPIO pin direction to be an output.

GPIO27 is just connected to a CPLD input without any pull-ups or pull-
downs.  If GPIO27 is left as an input, it will float around mid-supply,
which for CMOS inputs is the worst place for a pin to be.  Ensure that
this pin is driven.

Subject: ARM: sa11x0: neponset: fix interrupt setup

Since ARM was converted to genirq, the neponset IRQ implementation has
gradually broken as a result of various subtle changes being introduced
into genirq.

It used to be that simple IRQs did not need an IRQ chip.  This is no
longer the case, and genirq barfs in irq_set_handler().  Fix this by
introducing a dummy no-op chip, and registering it along with the flow
handler.

Neponset IRQs really don't have any masking ability - all we have is a
status register to allow us to decode the source, and a three input OR
gate inside a CPLD.

Subject: ARM: sa11x0: neponset: implement support for sparse IRQs

Implement the necessary allocation/freeing functionality to support
sparse IRQs with the Neponset device.  On non-sparse IRQ platforms,
this allows us to dynamically allocate from within the available IRQ
number space.
