[PATCH v3 0/6] ARM: make mach/hardware.h optional

From: Rob Herring

From: Rob Herring <rob.herring@xxxxxxxxxxx>

Currently, all ARM platforms must have a mach/hardware.h include. This is
because it is ultimately included by linux/pci.h which is included in many
places even for !CONFIG_PCI.

This could be fixed simply with an ifdef around the include of mach/hardware.h
in asm/pci.h. However, in the interest of fixing this for single kernel
binary builds, this series removes the include of mach/hardware.h outside of
mach-* and plat-*. What's used from hardware.h is a couple of PCI defines.
Converting them to variables allows each platform to set the values as needed.

This does not address the inclusion of mach/hardware.h under drivers/*. This
appears to be mostly older platforms. There could also be some indirect
inclusions from other mach/* headers.

I've compile tested on most affected ARM platforms.

Changes from v2:
- Incorporated compile fixes for microblaze from Michal Simek.
- Added conversion of powerpc to generic pci flag functions.
- Combined powerpc and microblaze conversion to use
asm-generic/pci-bridge.h into one commit. Renaming of powerpc pci
flags functions is separate commit.
- Changed defaults for PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to 0x1000 and
0x1000000, respectively.
- Dropped commit moving ARCH_HAS_DMA_SET_COHERENT_MASK defines into
memory.h. This conflicts with other clean-up work by Nicolas Pitre.

Changes from v1:
- Added patch 2 to move ARCH_HAS_DMA_SET_COHERENT_MASK defines into memory.h.
- Separated VGA changes and renamed to vga_base.
- Reverted mach/hardware.h removal from ecard.c. It's getting implicitly
included anyway.
