state: backend_raw: add hmac support ...

This patch adds hmac support to the raw backend.

With this patch, modifications of the header or data of a state partition can
be detected, as the hmac woudln't match anymore. The hmac relies on a shared
secret, which is requested from the keystore, with keystore_get_secret() using
the name of the state partition as the "name" of the secret.

of_path: Allow pointing directly to the partition ...

We could only point to partitions in the device tree by using
&norflash, "partname:barebox-environment". Allow to point to the
partition directly without having to parse the partition labels.

mtd: m25p80: make it possible to use large blocks if desired ...

Some SPI NOR flashes support 4K erase blocks. 4K erase blocks do not
work with UBIFS which needs a minimum erase block size of 15360 bytes.
Also bigger sectors are faster to erase. This patch adds a device tree
option to use the bigger blocks instead of the default 4K blocks.

video: implement framebuffer console ...

This patch realizes framebuffer console support for barebox. It
supports colors and enough escape sequences to show the barebox
console and editor properly.

fbconsole mini-HOWTO
====================

1. compile sandbox barebox with

    CONFIG_VIDEO=y
    CONFIG_FRAMEBUFFER_CONSOLE=y
    CONFIG_DRIVER_VIDEO_SDL=y

2. run barebox

3. test fbconsole

    fbconsole0.active=oe

ARM: vincell: move to DT probing ...

This enabled multi image support for the Garz&Fricke Vincell board. Also
it adds the Vincell-LT as a second image with a separate device tree.
Previously we used the same image on both the Vincell and the Vincell-LT
image since the differences are not that significant for barebox. Still
this was good for quite some confusion internally, so let's properly
introduce a second image.

blspec: Automatically append rootarg ...

This patch makes it possible to automatically add a suitable root= option
for booting Linux from the same filesystem on which the bootspec entry
has been found. This adds an additional 'linux-appendroot' option to
bootspec which if set to 'true' will cause barebox to automatically
add a root= option. This currently works for NFS, UBIFS and regular
block devices like ATA, SD/MMC using the root=PARTUUID= mechanism.
