With CONFIG_PARTITION_NEED_MTD enabled we use mtd rather than devfs
directly to create partitions on mtd devices. Since:

| mtd: nand: bb: use mtd api directly
|
| The devfs layer just adds an addition indirection between mtd
| and the bb devices with no purpose. Drop it.

The bad block aware device creation doesn't work if this option
is disabled. With this we remove CONFIG_PARTITION_NEED_MTD and always
use mtd partitions on mtd devices.

Simple update file format developed for Somfy, tools and library are
available under LGPLv2 (https://www.gitorious.org/libbpk).
This format in the v1.0 allow you to store 6 types a binary stream for
a unique hardware id:
- bootloader
- bootloader_version
- description.gz
- kernel
- rootfs
- firmware_version
and you can easly add more binary stream type.
The fs will display you in a directory per hw id
and if a binary stream type is unknown will be display
as unknown_%08x
# mount image.bpk /tmp
# ls -l /tmp/hw_id_0/
-rwxrwxrwx 10 firmware_version
-rwxrwxrwx 8 firmware_version.crc
-rwxrwxrwx 1845968 kernel
-rwxrwxrwx 8 kernel.crc
-rwxrwxrwx 5062656 rootfs
-rwxrwxrwx 8 rootfs.crc
-rwxrwxrwx 248 bootloader
-rwxrwxrwx 8 bootloader.crc
-rwxrwxrwx 248925 description.gz
-rwxrwxrwx 8 description.gz.crc
-rwxrwxrwx 4 bootloader_version
-rwxrwxrwx 8 bootloader_version.crc
-rwxrwxrwx 4 unknown_1234567g
-rwxrwxrwx 8 unknown_1234567g.crc
Why BPK and not CPIO or uImage
1) CPIO
cpio does not handle > 4GiB image and does not have any crc checksum
2) uImage
uImage only provide one crc32 for the all data part and only a list of binary
stream with no information about what is what (in multi-image format)
3) BPK
BPK provide a crc32 for the header part and one crc32 per binary stream
so if you does not care of some data you are not force to check them
And you known exactly the binary stream type and for which hw to
use it.

you can get the image header via an ioctl on any file
UIMAGEFS_METADATA
if you want to check the crc do
# crc32 -f /tmp-multi/data -V /tmp-multi/data.crc
CRC32 for /tmp-multi/data 0x00000000 ... 0x000008ee ==> 0x88d5a0db

This adds ubifs support from u-boot-2013.07. This is taken
mostly as-is, only the necessary adjustments to attach to the
barebox fs layer have been made.

The ext4 implementation has been taken from U-Boot with some
changes:
- No global variables to allow for multiple filesystems to
be mounted and multiple files to be open.
- remove fs internal link following and use the barebox link
implementation.
- remove write support. This is incomplete in U-Boot, so I decided
to skip this for now.

The tftp filesystem support is by no means dependent on the old tftp
support, it depends on NET though.

This patch adds readonly NFS support. Currently no links are supported.
This is based on the previous U-Boot/NetBSD based code and some Kernel
bits.

This patch adds an automount command which makes it possible
to execute a script when a certain directory is first accessed.
It's the commands responsibility to make this directory available
(bringing devices up and mounting it). This results in automount
support which makes sure that from the shell every file can
be accessed without having to care for device bringup. Bringing
up devices may be expensive (USB, dhcp). The automount support
makes it easy for the environment to bringup devices when they
are actually needed.

This adds tftp filesystem support. It currently duplicates
significant amounts of the tftp (command) support. This is ok
since we can eventually drop the original tftp command later.
tftp is not really suitable to be handled as a filesystem. It lacks
support for stat, reading directories and other things. Handling
it as a filesystem has one big advantage though: tftp is no special
case for boot scripts and/or commands anymore which makes them simpler.
This implementation has some improvements to the original tftp command.
It supports blocksize negotiation which speeds up transfers if the tftp
server supports it. Also we can determine the filesize to transfer if
the remote end supports it.

This patch offers a read/write implementation for barebox. The code
does not exaclty match barebox coding style, but works nicely and
should be ready to give it a try.
