The interface emulates the Linux commands, except that you can
specify a sub area - E.G.:
barebox:/ md5sum /dev/fd0 2M+1M /env/config /env/bin/boot 10+2
61c4c0180b044191d28f27545f43562f /dev/fd0 0x00200000 ... 0x00300000
908b84bcbadd2f263583a65ff31d1cad /env/config 0x00000000 ... 0x000003a7
f23bd15825cc5006cf5f9fd486d82d2d /env/bin/boot 0x0000000a ... 0x0000000c
Adds around 1400 bytes (+ size of digest code) with everything enabled.

Normally the default path to save the environment is /dev/env0. However,
we can't map a file in a fat filesystem to /dev/env0. So if we want to
store the environment in a file in fat we have to make it configurable.

The old way happily removed cdev entries which were no bb dev
at all. Fix this by checking if the given device actually is
a bb device.

The cdev operations are available without the complete file API,
so they are more suitable for internal usage.

It's good to seperate the code which others can use from commands.
This way other users do not depend on the command being compiled in.

Environment variables are only useful in interactive environments.
Make it optional on our way to support a noninteractive barebox.

This patch makes the USB command optional and makes usb_rescan a
global function. This way we can use USB in noninteractive
environments.

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

The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().
This patch also fixes code which didn't check for NULL from malloc() etc.
Usage: malloc(), memalign() return NULL when out of RAM.
xmalloc(), xmemalign() always return non-NULL or panic().

The m68k support is compile broken for a long time now and nobody
cared so far. We cannot keep the architecture uptodate with current
development wihtout being able to compile it. It's still in the
archives and can be re-added anytime once somebody cares for.
