Will Deacon de4338f40e ARM: 6048/1: ARM: iop3xx: register PMU IRQs during board initialisation
This patch adds an initcall for the iop3xx platforms so that they
register their PMU IRQS with the PMU framework in the Kernel.

Dan Williams 2492c84518 iop3xx: surface the iop3xx DMA and AAU units to the iop-adma driver
Adds the platform device definitions and the architecture specific support
routines (i.e. register initialization and descriptor formats) for the
iop-adma driver.

Changelog:
* add support for > 1k zero sum buffer sizes
* added dma/aau platform devices to iq80321 and iq80332 setup
* fixed the calculation in iop_desc_is_aligned
* support xor buffer sizes larger than 16MB
* fix places where software descriptors are assumed to be contiguous, only
  hardware descriptors are contiguous for up to a PAGE_SIZE buffer size
* convert to async_tx
* add interrupt support
* add platform devices for 80219 boards
* do not call platform register macros in driver code
* remove switch() statements for compatible register offsets/layouts
* change over to bitmap based capabilities
* remove unnecessary ARM assembly statement
* checkpatch.pl fixes
* gpl v2 only correction
* phys move to dma_async_tx_descriptor

Dan Williams 3668b45d46 [ARM] 4187/1: iop: unify time implementation across iop32x, iop33x, and iop13xx
* architecture specific details are handled in asm/arch/time.h
* ARCH_IOP13XX now selects PLAT_IOP
* as suggested by Lennert use ifdef CONFIG_XSCALE to skip the cp_wait on
XSC3

Dan Williams 588ef76935 [ARM] 4184/1: iop: cp6 access handler (undef_hook)
Enable svc access to cp6 via an undefined instruction hook.  Do not enable
access for usr code.

This patch also makes iop13xx select PLAT_IOP, this requires a small change
to drivers/i2c/busses/i2c-iop3xx.c.

Per Lennert Buytenhek's note, the cp6 trap routine is moved to arch/arm/plat-iop
Per Nicolas Pitre's note, the cp_wait is skipped since the latency to
return to the faulting function is longer than cp_wait.

Dan Williams 6df26700c0 [ARM] 4182/1: iop3xx: fix the ioremap implementation to not remap static ranges
Implement a custom ioremap implementation for iop3xx. This saves
establishing new mappings. It also cleans up the PCI IO resource to be a
physical address rather than a virtual address as Russell pointed out on
the original iop13xx port.
