Two changes are necessary to enable proper operation of the DM9000 device with
the Colibri PXA 270 board: firstly, the IRQ type needs to be configured for
rising edge interrupts, and secondly this configuration needs to be
communicated through to the DM9000.

Whereas most Orion 5x machine support code would initialise the PCI
subsystem with nr_controllers in their struct hw_pci set to 2, the
DNS323 and Kurobox Pro machine support code had nr_controllers set
to 1.
This was presumably done because on those two machines, the PCI(-X)
controller (nr == 1) isn't used, requiring initialisation of only
the PCIe controller (nr == 0.) However, not initialising the PCI(-X)
controller on boards that don't use it leads to a situation where
both the PCIe and the PCI(-X) controller think that their root bus is
zero, and it messes up IRQ assignment.
This patch changes the DNS323 and Kurobox Pro support code to always
use nr_controllers == 2.

The CPU's dma_flush_range() operation needs to clean+invalidate the

Fix initialization of framebuffer not calling ioremap_writecombine() function
and not using internal SRAM for at91sam9rl.
This is a little rework of the "Don't initialize a pre-allocated framebuffer"
patch that corrects the call to ioremap_writecombine() function.
It also cuts the use of internal SRAM for at91sam9rl : it is a bit small
for a framebuffer.

A lot of stuff in spitz/akita/etc. depends on corgi_ssp to be initialised
early. However corgi_ssp initialisation fails, because at that time pxa*-ssp
devices don't have drivers. Move ssp earlier in the makefile so they are
registered before corgi-ssp.
Also move sleep/suspend and cpu-freq to more logical places

RCSR is only present on PXA2xx CPUs, not on PXA3xx CPUs. Therefore,
we should not be unconditionally writing to RCSR from generic code.
Since we now clear the RCSR status from the SoC specific PXA PM code
and before reset in the arch_reset() function, the duplication in
the corgi, poodle, spitz and tosa code can be removed.

This replaces the duplicated arch-specific versions of "sys_pipe()" with
one unified implementation. This removes almost 250 lines of duplicated
code.
It's marked __weak, so that *if* an architecture wants to override the
default implementation it can do so by simply having its own replacement
version, since many architectures use alternate calling conventions for
the 'pipe()' system call for legacy reasons (ie traditional UNIX
implementations often return the two file descriptors in registers)
I still haven't changed the cris version even though Linus says the BKL
isn't needed. The arch maintainer can easily do it if there are really
no obstacles.
