The flags in struct console_device have to be initialized
to zero. Otherwise the following can happen:
- console_register sets the initial baudrate of a new console
before we set the global console init state to CONSOLE_INIT_FULL.
- In console_baudrate_set we test whether the current console is
active which may be true because of unitialized flags.
- we then call getc() to wait for the user to accept the new settings
and we are stuck because of the CONSOLE_UNINITIALIZED state
we will never get anything from getc().
Looking back this explains some cases for me when barebox refused
to start and I really wonder why this did not become a more visible
problem before.

Add a device to read and write to MTD data and oob
(/dev/mtdraw<N>).
The device is constrained in a separate source file, so that
further improvement of commands (such as nandwrite) could
make it useless, and easy to remove.

If multiple MTD devices were registered, an exception
occured, as they all wanted id 0. Let the driver code choose

Change NAND_WRITE into MTD_WRITE.
Change "page_shift" references in the core, which are purely
NAND, into mtd->writesize which is MTD generic.
Rename all "info" (struct mtd_info) into "mtd".
Also provide a parameter to add_mtd_device() so that legacy
nand devices still appear as nand<N>.

It makes no sense to check the filename pointer here, because a) we have
already been using it and b) argc has been tested against 1 already, so
argv[1] should not be NULL. So, drop the checks.

Added i2c support for omap4. Tested on pcm049.
Driver based on linux kernel implementation.
Also added a shift to access 16-bit registers
to make support for OMAP730/850 possible.
If accessing a non existing slave the bus will go into arbitration mode.
It's unable to recover from it.

Increase pxa reading performance by reading 4 bytes at a
time instead of 4 reads of 1 byte.
As the mci controller FIFO accepts reads on bytes, halfwords
or words, use words whenether possible.
The boost is for a 250KBytes file read and display (bmp):
- before: 6900ms
- after: 6000ms

The NAND_READ_OOB Kconfig option is used to
a) creating a cdev for reading OOB data
b) compiling in mtd->read_oob support
The former was intended and that's also what the Kconfig help
says. The latter though was implicit and wrong. mtd->read_oob
is also used by the bbt code which resulted in a NULL pointer
deref when compiled with BBT but without NAND_READ_OOB.
To fix this, split the option into two. The now invisible
option NAND_OOB_DEVICE is only responsible for b) and gets
selected when necessary.
