MIPS: ath79: drop legacy IRQ code
With the target now being fully OF based, we can drop the legacy IRQ code.
All IRQs are now handled via the new irqchip drivers.

MIPS: ath79: add support for QCA953x QCA956x TP9343
This patch adds support for 2 new types of QCA silicon. TP9343 is
essentially the same as the QCA956X but is licensed by TPLink.

07ba4b061a irqchip/ath79-misc: Move the MISC driver from arch/mips/ath79/
The driver stays the same but the initialization changes a bit.
For OF boards we now get the memory map from the OF node and use
a linear mapping instead of the legacy mapping. For legacy boards
we still use a legacy mapping and just pass down all the parameters
from the board init code.

c166fe78d0 MIPS: ath79: Allow using ath79_ddr_wb_flush() from drivers
Move the declaration of ath79_ddr_wb_flush() to asm/mach-ath79/ath79.h
to allow using it from drivers. This is needed to move the CPU IRQ
driver to drivers/irqchip.

24b0e3e84f MIPS: ath79: Improve the DDR controller interface
The DDR controller need to be used by the IRQ controller to flush
the write buffer of some devices before running the IRQ handler.
It is also used by the PCI controller to setup the PCI memory windows.

The current interface used to access the DDR controller doesn't
provides any useful abstraction and simply rely on a shared global
pointer.

Replace this by a simple API to setup the PCI memory windows and use
the write buffer flush independently of the SoC type. That remove the
need for the shared global pointer, simplify the IRQ handler code.

[ralf@linux-mips.org: Folded in Alban Bedel's follup fix.]

in various code paths.  We have determined the SoC revision already, so we

d4a67d9dc8 MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs
This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:

  - AR7130
  - AR7141
  - AR7161
  - AR9130
  - AR9132
  - AR7240
  - AR7241
  - AR7242

The current patch contains minimal support only, but the resulting
kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.
