AT91 has one include loop in its header files:
include/asm-arm/io.h <- include/asm-arm/arch-at91/io.h <-
include/asm-arm/io.h
Circular include dependencies are dangerous since they can result in
inconsistent definitions being provided to other code, especially if
'#ifndef' constructs are used.
Solve this by removing the offending includes. Built tested using my
AT91 configuration.

Resolve the circular dependency in the AT91 header files (io.h and
hardware.h) by moving the at91_sys_read() and at91_sys_write() functions
to io.h

Now that Linux includes support for the Atmel AT91SAM9260 and
AT91SAM9261 processors in addition to the original Atmel AT91RM9200
(with support for more AT91 processors pending), the "mach-at91rm9200"
and "arch-at91rm9200" directories should be renamed to indicate their
more generic nature.
The following git commands should be run BEFORE applying this patch:
git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91
