This introduces a new NAND_BUSWIDTH_AUTO flag which can be used
to automatically detect the nand buswidth. The id is always read
in 8bit mode. An additional callback is needed to switch the nand
controller into 16bit mode.
This currently depends on a safe read_byte (always) and read_buf
(for onfi-only flashes) callback. It has been tested on OMAP, but
is not something that generally works. For this reason the existence
of the set_buswidth callback is used to determine whether we are
able to do autodetection or not.

From Linux commit 69349c2dc01c489eccaa4c472542c08e370c6d7e:
Using IS_ENABLED() within C (vs. within CPP #if statements) in its
current form requires us to actually define every possible bool/tristate
Kconfig option twice (__enabled_* and __enabled_*_MODULE variants).
This results in a huge autoconf.h file, on the order of 16k lines for a
x86_64 defconfig.
Fixing IS_ENABLED to be able to work on the smaller subset of just
things that we really have defined is step one to fixing this. Which
means it has to not choke when fed non-enabled options, such as:
include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef]
The original prototype of how to implement a C and preprocessor
compatible way of doing this came from the Google+ user "comex ." in
response to Linus' crowdsourcing challenge for a possible improvement on
his earlier C specific solution:
#define config_enabled(x) (__stringify(x)[0] == '1')
In this implementation, I've chosen variable names that hopefully make
how it works more understandable.

The standard devices are currently broken since they have
the size ~0. As now files use loff_t as file size which is a signed
type the read implementation gets confused and now returns -1.
The current implementation also has the (somewhat theorical) problem
that we do not have real streaming devices, so /dev/zero went out
of zeroes after reading 4GB (or now LLONG_MAX).
This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new
file size flag FILE_SIZE_STREAM which makes it possible to create
real stream devices instead.

global linux.bootargs.ip="ip=dhcp"
global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)"

string during boot.

cramfs does not compile since we updated zlib to the kernel
version. Fix this by using the kernel version of uncompress.c

uncompress() has the same prototype as the various kernel decompress
functions. It automatically detects the compression type and selects
the correct uncompress function.

Several filetypes can be autodetected. Barebox could make use
of this in several ways:
- Add a command to detect filetypes
- detect arm zImages and uImages to unify the different boot commands
- maybe detect UBI or JFFS2 images to construct parts of the kernel
command line
- select correct uncompression function based on filetype
This patch adds basic support to detect filetypes.

The kernel uncompression functions have a unified API. Switch
to the kernel implementation to unify the different uncompression
APIs. As a bonus the kernel implementation is much smaller.
