Currently early kernel messages, i.e., those from uncompression, go to the
debugging UART. And if it is enabled in the platform configuration, but
not initialized by the bootloader, the machine hangs, waiting for UART
status change. Besides, having those messages on another UART - typically
the console UART - may be preferrable. This patch allows selecting the
UART in kernel configuration.

Remove the legacy PIO pin definitions for the AT91 processors.
The standard (and portable between the different AT91 processors) method
is to use the AT91_PIN_* defines and the GPIO API.

Add support for the Atmel AT91SAM9XE range of processors. These are
basically AT91SAM9260's with different amounts of internal SRAM and
Flash.
We make use of the existing AT91SAM9260 support, but just perform
run-time detection of the size of the internal SRAM.

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
