The i.MX23 comes with a special UART dedicated for debugging purposes. This one
is mostly used for the console the user can reach.

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.

Adding MCI card support for STM378x/i.MX23 CPUs. This is for reference only,
as this architecture is currently not part of barebox (but will coming soon).
Its tested on the i.MX23 based ChumbyOne.

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.

Using a temp. buffer for a disk sector on the stack, seems not work. Doing so
lets the system run crazy (the stack seems to be destroyd). Don't know the
correct stack handling on ARM, but (IMHO) I also can exclude any writing across
the buffer boundaries.
Using a temp. buffer via malloc() runs also on ARM.
Note: This patch was required to add MCI card support, which can be handled
like a disk drive.

In real life this output is only a "nice to have", but most of the time
its useless and confusing. So, make it a debug feature for the interested
developer.
Note: This is in preparation to add MCI card support, which mostly come with
a partition table and can be handled like a disk drive.

it's allow you to compile specific defconfig or ARCH or all
as
CROSS_COMPILE=arm-linux- ARCH=arm ./MAKEALL at91sam9263ek_defconfig
CROSS_COMPILE=arm-linux- ARCH=arm ./MAKEALL
The cross-compiler can be specify via
CROSS_COMPILE default
CROSS_COMPILE_<arch> arch default
CROSS_COMPILE_<target> deconfig specifc
it will be evaluated in the invert order
or via config
you can specify it via env CONFIG or option -c (overwrite env)
CONFIG=./MAKEALL.cfg ARCH=arm ./MAKEALL at91sam9263ek_defconfig
CONFIG=./MAKEALL.cfg ARCH=arm ./MAKEALL
and for all
CONFIG=./MAKEALL.cfg ./MAKEALL
you can specify via env or option
env option

Makes sure that the STOP condition is transmitted before the I2C
controller is disabled.
This fixes a problem where writing to an external EEPROM was not working
because the EEPROM waits until the STOP before initiating the write
internally.
