Flushing the L1 D cache with a test/clean/invalidate loop is very
easy in software, but it is not the quickest way of doing it, as
there is a lot of overhead involved in re-scanning the cache from
the beginning every time we hit a dirty line.

This patch makes proc-feroceon.S use "clean+invalidate by set/way"
loops according to possible cache configuration of Feroceon CPUs
(either direct-mapped or 4-way set associative).

The mv643xx_eth platform data field ->force_phy_addr only needs
to be set if the passed-in ->phy_addr field is zero (to distinguish
the case of not having specified a phy address
(force_phy_addr = 0) from the case where a phy address of zero needs
to be used (force_phy_addr = 1.))

Also, the ->force_phy_addr field will hopefully disappear in a
future mv643xx_eth reorganisation.

Therefore, this patch deletes the ->force_phy_addr field initialiser
from all Orion board code.

If all PCI devices are working as expected, the error printks in the
various implementations of ->map_irq() doesn't really provide any
useful info.  And if something is not working as expected, turning
on pci=debug gives you more useful information than the printk calls
in ->map_irq(), since the former also tells you which devices _did_
get IRQs successfully assigned.  Therefore, delete these printks
entirely.

Instead of having board code poke directly into the MPP configuration
registers, and separately calling orion5x_gpio_set_valid_pins() to
indicate which MPP pins can be used as GPIO pins, introduce a helper
function for configuring the roles of each of the MPP pins, and have
that helper function handle gpio validity internally.

It makes no sense to do PCIe WA window setup in the individual
board support files while the decision whether or not to use the
PCIe WA access method is made in a different place, in the PCIe
support code.

This patch moves the configuration of a PCIe WA window from the
individual Orion board support files to the central Orion PCIe
support code.

This patch moves initialisation of EHCI/I2C/UART platform devices
from the common orion5x_init() into the board support code.

The rationale behind this is that only the board support code knows
whether certain peripherals have been brought out on the board, and
not initialising peripherals that haven't been brought out is
desirable for example:
- to reduce user confusion (e.g. seeing both 'eth0' and 'eth1'
  appear while there is only one ethernet port on the board); and
- to allow for future power savings (peripherals that have not
  been brought out can be clock gated off entirely).

Make it clear that Orion top-level IRQs are level-triggered.  This
means that we don't need an ->ack() handler, or at least, we don't
need the ->ack() handler (or the acking part of the ->mask_ack()
handler) to actually do anything.

Given that, we might as well point our ->mask_ack() handler at the
->mask() handler instead of providing a dummy ->ack() handler, since
providing a ->mask_ack() handler on level IRQ sources will prevent
->ack() from ever being called.

The DRAM base address and size fields in the CPU's MBUS bridge have
64KiB granularity, instead of the currently used 16MiB.  Since all
of the currently supported MBUS peripherals support 64KiB granularity
as well, this patch changes the Orion address map code to stop
rounding base addresses down and sizes up to multiples of 16MiB.

Currently, Orion window setup uses hardcoded window indexes for each
of the boot/cs0/cs1/cs2/PCIe WA windows.  The static window allocation
used can clash if board support code will ever attempt to configure
both a dev2 and a PCIe WA window, as both of those use CPU mbus window
#7 at present.

This patch keeps track of the last used window, and opens subsequently
requested windows sequentially, starting from 4.  (Windows 0-3 are used
as MEM/IO windows for the PCI/PCIe buses.)

The implementation for memory copy functions on ARM had a (disabled)
provision for aligning the source pointer before loading registers with
data.  Turns out that aligning the _destination_ pointer is much more
useful, as the read side is already sufficiently helped with the use of
preload.

So this changes the definition of the CALGN() macro to target the
destination pointer instead, and turns it on for Feroceon processors
where the gain is very noticeable.

The inline assembly in drivers/watchdog/hpwdt.c was incredibly broken,
and included all the function prologue and epilogue stuff, even though
it was itself then inside a C function where the compiler would add its
own prologue and epilogue on top of it all.

This then just _happened_ to work if you had exactly the right compiler
version and exactly the right compiler flags, so that gcc just happened
to not create any prologue at all (the gcc-generated epilogue wouldn't
matter, since it would never be reached).

But the more proper way to fix it is to simply not do this.  Move the
inline asm to the top level, with no surrounding function at all (the
better alternative would be to remove the prologue and make it actually
use proper description of the arguments to the inline asm, but that's a
bigger change than the one I'm willing to make right now).
