This just leaves include/asm-arm/plat-* to deal with.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

This patch adds the basic support for the em7210 board. It is similar to
the iq31244 board and can be found on Intel "Baxter Creek" ss4000e nas.

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

Currently the iop3xx platform support code assumes that RedBoot is the
bootloader and has already initialized the ATU. Linux should handle this
initialization for three reasons:
1/ The memory map that RedBoot sets up is not optimal (page_to_dma and
virt_to_phys return different addresses). The effect of this is that using
the dma mapping API for the internal bus dma units generates pci bus
addresses that are incorrect for the internal bus.
2/ Not all iop platforms use RedBoot
3/ If the ATU is already initialized it indicates that the iop is an add-in
card in another host, it does not own the PCI bus, and should not be
re-initialized.
Changelog:
* rather than change nr_controllers to zero, simply do not call
pci_common_init

* 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

get_irqnr_preamble allows machines to take some action before entering the
get_irqnr_and_base loop. On iop we enable cp6 access.
arch_ret_to_user is added to the userspace return path to allow individual
architectures to take actions, like disabling coprocessor access, before
the final return to userspace.
Per Nicolas Pitre's note, there is no need to cp_wait on the return to user
as the latency to return is sufficient.

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.

Since the iop32x code isn't iop321-specific, and the iop33x code isn't
iop331-specfic, do a s/iop321/iop32x/ and s/iop331/iop33x/, and tidy up
the code to conform to the coding style guidelines somewhat better.

Revamp the iop3xx board support: move the support code for each iop
board type into its own file, start using platform serial and platform
physmap flash devices, switch to a per-board time tick rate, and get
rid of the ARCH_EP80219 and STEPD config options by doing the relevant
checks at run time.

Add CP6 enable/disable sequences to the timekeeping code and the IRQ
code. As a result, we can't depend on CP6 access being enabled when
we enter get_irqnr_and_base anymore, so switch the latter over to
using memory-mapped accesses for now.
