Subject: [PATCH 0/8] enable support for AMBA drivers under x86

From: Davide Ciminaghi <ciminaghi@...dd.com>

Following Alessandro's report on build errors for amba drivers under x86
(see [1]), here's a patchset fixing the errors and adding a pci-amba bridge
driver.
Some notes:

* 1/8 (DMA: PL330 ...) is quite fat. Should this be a problem, we
could simply disable the PL330 driver under non ARM systems (we actually
don't need the PL330 driver for our x86 platform).
* All the mmc drivers have been fixed to use the new linux/sizes.h header.
* As far as the mmci driver is concerned, readsl/writesl have been replaced
by ioread32_rep/iowrite32_rep as suggested by Arnd Bergmann (see [2]).
* asm/amba/pl080.h is needed by arch/arm/mach-s3c64xx/dma.c (registers
definitions, struct pl080s_lli), so we need most of it to be globally
visible. As a consequence Arnd's suggestion (see [2]) about splitting
the file into two parts was not followed for now.

Alessandro Rubini (7):
  DMA: PL330: use prefix in reg names to build under x86
  gpio: pl061 depends on ARM
  pl080.h: moved from arm/include/asm/hardware to include/linux/amba/
  watchdog: sp805_wdt depends on ARM
  mmc: use the new <linux/sizes.h>
  drivers/amba: add support for a PCI bridge
  x86: add CONFIG_ARM_AMBA, selected by STA2X11

Davide Ciminaghi (1):
  mmci: replace readsl/writesl with ioread32_rep/iowrite32_rep
