To allow for proper initialisation of the SMSC9115 Ethernet chip
and other devices which may be connected to the 'external bus',
Device Tree must first enable and traverse though it. This patch
enables the 'external bus' which will facilitate further
initialisation of its suborantate DT nodes.

It is believed that the gpio compatible match entry is too long

Low EMI (Electro-Magnetic Interference) mode means lower slew
rate on the signals. The Nomadik GPIO controller supports
this so create an interface to enable it.

The register and irq definitions in mach/*.h for spear3xx and
spear6xx are now mostly obsolete, after the platforms have been
converted to device tree based probing and the data is now
part of the device tree files.
The misc_regs.h contents are moved into clock.c because that is
the only user, aside from the DMA_CHN_CFG that should eventually
get handled differently. Some of the contents of mach/spear.h
still remain, because they are used to set up the static map table,
timer, uart and auxdata tables, but almost everything got removed.
We might remove everything but the map table as the DT conversion
completes, but that is not a priority. I've also made sure to
make both copies of spear.h more or less identical so we can
eventually combine them.
The spear3?0.h files were only used by the spear3?0.c files, so I
merged the contents in there and removed the bits that were unused.
This is something that should still be looked at.

Recently device tree support is added for SPEAr3xx & SPEAr6xx and we must

This patch adds a generic target for SPEAr3xx machines that can be configured
via the device-tree. Currently the following devices are supported via the
devicetree:
- VIC interrupts
- PL011 UART
- PL061 GPIO
- PL110 CLCD
- SP805 WDT
- Synopsys DW I2C
- Synopsys DW ethernet
- ST FSMC-NAND
- ST SPEAR-SMI
- ST SPEAR-KEYBOARD
- ST SPEAR-RTC
- ARASAN SDHCI-SPEAR
- SPEAR-EHCI
- SPEAR-OHCI
Other peripheral devices will follow in later patches.
This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of
4K for individual peripherals. This is done to have efficient TLB lookup for any
I/O windows that are located closely together. ioremap() on this range will
return this mapping only instead of creating another.

Nicolas Ferre <nicolas.ferre@atmel.com> writes:
First batch of AT91 cleanup for 3.5 kernel.
- The biggest improvement of this series is the ability to compile several
AT91 SoCs in one kernel image.
For now on it's limited to the DT-enabled boards but we can compile all
the core together.
- The Kconfig series is stacked before other patches as it is simple and
non-intrusive. Its goal is to remove too restrictive dependencies on
SoC names. This will allow to add support for newer SoC seamlessly.
- Some very "cosmetic" Kconfig changes are also added (entry names,
comments, etc.).
