In a noninteractive environment barebox will be compiled without
command support. So move version_string to a seperate file which
is compiled unconditionally.
Also, display the banner when the simple console support is used.

This makes it possible to compile without devfs. devfs_create/devfs_remove
is used by drivers and thus must still be present even without devfs support.
Also, this patch adds cdev_open/cdev_close/cdev_flush/cdev_ioctl calls to
work with devices without using the file api.

This patch adds Altera UART driver. Kconfig and Makefile are
updated to include this new driver.

The nand command is for bad block handling which some do not need.
So make it optional, but with default y.

This patch adds BCH ecc support to the omap nand driver. The BCH
error correction allows for up to 8 bit error correction. It is
also needed for booting from nand on omap4.
This is based on code from Sukumar Ghorai <s-ghorai@ti.com>:
[PATCH] omap3: nand: bch ecc support added

On omap we use different ecc modes for different purposes. The initial
boot code has to be written with hardware ecc whereas Linux usually uses
software ecc. To be able to write in both modes with a sinlge barebox
image introduce a eccmode device parameter.

If compiled without gpio support the linker will throw the
gpio functions away anyway, so make the omap kconfig entries
a bit easier.

Give this omap specific entry an omap namespace. Also, remove
unnecessary dependency to omap2/3 in nand Kconfig.

The original plan was to add all omap devices into the boards/omap
directory. Anyway, there will be reasons to put a board somewhere
else, so move the generic parts into the omap architecture directory.

The current gpio support is derived from the kernel which allows
for support for omap2/3/4 in a single kernel. We do not need this
here, so make it more simple to be able to add omap4 support later.

Otherwise we end up with errno not being set correctly
if a filesystem driver uses the standard open/close/read/write
functions to access its backing store.
