AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed.
The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board.
It is essentially the same, with a few minor differences.

AT91_BASE_EMAC is never used outside the board specific files,
so replace its usage by the board specific AT91xxx_BASE_EMAC.

AT91_ID_US0 / AT91_ID_US1 / AT91_ID_US2 were used but never defined.
Since they are never used outside the board specific files, they can
be replaced by the board specific AT91xxx_ID_US0 / AT91xxx_ID_US1 /
AT91xxx_ID_US2.
Bug spotted by Jesus Alvarez <jalvarez@micromint.com>.

On the at91sam9260ep development board there is an EEPROM
connected to the TWI interface (PA23, PA24 Peripheral A
multiplexing), so we cannot use these pins as ETX2, ETX3.
This patch configures PA10, PA11 pins for ETX2, ETX3
instead of PA23, PA24 pins.

AT91 RSTC registers are battery-backuped, so their values
are not reset across power cycles. One of those registers,
the AT91_RSTC_MR register, is being modified by U-Boot, in
the ethernet initialisation routine, to generate a 500ms
user reset.
Unfortunately, this value is not being restored afterwards,
causing subsequent resets to also last for 500ms.
This long reset sequence causes problems (at least) in the
boot sequence from NOR: by the time the CPU tries to load
a program from the NOR flash, the latter is still in reset
and not yet available.
Additionaly, this patch fixes a bug in the original code which
caused the reset delay to last for 2s instead of 500ms.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

The Atmel boards can handle 8 or 16 bit NAND memories. This patch
makes the support configurable in the board config header file
(CFG_NAND_DBW_8 or CFG_NAND_DBW_16).

When doing the AT91CAP9/AT91SAM9 port, a number of header files were
copied from the Linux kernel sources. This patch explicitly specifies
this origin for all the copied headers, and for those missing copyright
information, adds it.
Additionaly, the header file 'at91sam926x_mc.h' has been superceeded
in the latest kernel sources by 'at91sam9_smc.h'.
The copyright information has been confirmed by the AT91 Linux kernel
maintainer, Andrew Victor <avictor.za@gmail.com>.

When applying the AT91CAP9 patches upstream, something transformed
the '@' character into the ' <at> ' sequence.
The patch below restores the original form in all the places where
it has been modified (the AT91CAP9 files, the AT91SAM9260 files which
were copied from AT91CAP9, and a couple of other files where the
' <at> ' sequence was present).
