These CPUs are called "i.MX", but they are of type STM378x from SigmaTel. They
do not share any devices with the other i.MX CPUs, so we need a separate
architecute directory to handle them without an ifdef hell in the native i.MX
files.

Adding MCI card support for S3C2440 CPUs. This is for reference only, as there
is currently no user in the barebox tree. Maybe one with access to the A9M2440
development kit can check it on his/her system.
Checked here with my own S3C2440 based system which is not in the barebox tree.

Guessing the size of an attached harddisk (access via x86 BIOS) was needed
due to the fact, barebox can't query this information from the BIOS easily.
But with the SD/MMC cards, there will be a second user of the generic disk
handling routines. And with this media it is very easy to know its size.
This patch provides a workaround to keep the guessing feature if the size of
the registered disk is 0. If it is not 0, the given value will be used instead.
Note: This is in preparation to add MCI card support, which can be handled
like a disk drive.

Fix watchdog's register size for the i.MX27 CPU
The watchdog registers on the i.MX27 CPU are 16 bit registers. This patch
just fixes the access macro.

Until now, the main function of the sandbox port wants to use the libc
getopt(), but as we have a getopt() implementation in barebox as well,
it is silently used instead. This works in the usual case, but if an
error occurs (i.e. by using an unknown argument) in getopt(), the
implementation tries to write to the console, which is not initialized
and thus breaks with a null pointer exception.
This patch changes the main function to use getopt_long() instead of
getopt(). This makes us use the implementation in glibc and while being
there, we get long options, which makes us look more professional...

Following steps lead to compilation error (barebox v2010.09.0):
1. make a9m2440_defconfig (or a9m2410) ARCH=arm
2. make CROSS_COMPILE=arm-linux- ARCH=arm
This patch should fix problems.

AT91sam9g20 is an evolution of the at91sam9260 with a faster clock
speed.
We created a new board for this device but based the chip support
directly on 9260 files with little updates.

Add OMAP3 architecture specific dcache flush back in.
Commit 78104ae181 isolates
the cache handling to appropriate handlers, but certain
architectures may need special handling esp during boot
time.
without this patch, building barebox with
omap3530_beagle_per_uart_defconfig
and attempting to use peripheral download with pusb/pserial
will fail as OMAP ROM code depends on 2nd stage bootloaders
to clean up things.
