menu: depend on !CONFIG_SHELL_NONE ...

It doesn't make much sense to have the menuframework but no
shell.

Fixes:
In function `menu_action_command': undefined reference to `run_command'

Add PBL console support ...

This adds simple console support to the PBL which makes it
possible to print more complex messages in the PBL than just
strings or hex numbers. For now puts_ll is used to print the
messages, so it depends on CONFIG_DEBUG_LL which makes it
more a debugging option. However, this could be extended later
to get regular output from the PBL if desired.

Kconfig: make BROKEN invisible ...

BROKEN is a developer option to keep things in the tree we know
are broken. Make this option invisible so that randconfig builds do
not enable it.

ARM: Let MMU depend on !CPU_ARM946E ...

leads to broken dependencies. Let MMU depend on !CPU_ARM946E instead.

blspec: depend on, not select flexible bootargs ...

Blspec is a consumer of the flexible bootargs mechanism, so it should
depend on it rather than select it.

Fixes:

which has unmet direct dependencies (COMMAND_SUPPORT && CMD_GLOBAL)

defaultenv-2: Make use of nonvolatile variables ...

This moves the variable assignments previously done in /env/config-board
to non volatile variables in /env/nv/. This makes the settings adjustable
by the user without editing a file.

Most of the changes are simple conversions which for many boards makes
/env/config-board unnecessary. Some boards had some logic to assign
global.boot.default based on the current bootsource. This has been
moved to /env/init/bootsource. An additional check is added to not
overwrite a nv.boot.default should it exist.

Introduce message logging support ...

This adds a buffer for log messages and a 'dmesg' command to
print the messages. The log buffer is implemented as log objects
rather than a string buffer. This makes it easy to implement
limiting the messages, cleaning the buffer and timestamping
the messages.

Add a Firmware programming framework ...

This framework handles a list of registered Firmware programming handlers
to unify a firmware programming interface by hiding the details how
to program a specific Firmware in its handler. This is created with FPGAs
in mind but should be usable for other devices aswell.
A user has two possibilities to load a firmware. A device file is create
under /dev/ which can be used to copy a firmware to. Additionally a
firmwareload command is introduced which can list the registered firmware
handlers and also to upload a firmware.

Add support for metadata in barebox images ...

It's often useful to get some information about a barebox image
before starting or flashing it. This patch introduces barebox
Image MetaData (IMD). When enabled a barebox image will contain
a list of tags containing the desired information. We have tags
for:

- the barebox release (2014.07.0-00160-g035de50-dirty)
- the build timestamp (#741 Mon Jul 28 15:08:54 CEST 2014)
- the board model the image is intended for
- the device tree toplevel compatible property

Also there is an additional generic key-value store which stores
parameters for which no dedicated tag exists. In this patch it
is used for the memory size an image supports.

Since there is no fixed offset in a barebox image which can be
used for storing the information, the metadata is stored somewhere
in the image and found by iterating over the image. This works
for most image types, but obviously not for SoC images which are
encoded or encrypted in some way.

There is a 'imd' tool compiled from the same sources for barebox,
for the compile host and for the target, so the metadata information
is available whereever needed.

For device tree boards the model and of_compatible tags are automatically
generated.

Example output of the imd tool for a Phytec phyFLEX image:

build: #889 Wed Jul 30 16:08:54 CEST 2014
release: 2014.07.0-00167-g6b2070d-dirty
parameter: memsize=1024
of_compatible: phytec,imx6x-pbab01 phytec,imx6dl-pfla02 fsl,imx6dl
model: Phytec phyFLEX-i.MX6 Duallite Carrier-Board

sandbox: allow "make ARCH=sandbox allyesconfig" ...

Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.

This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.

menutree: let it select GLOB and GLOB_SORT ...

The menutree doesn't select CONFIG_GLOB, but it depends on it. Without
it will just hang. So let it select it automatically. Also remove the
dependency of CONFIG_GLOB on CONFIG_HUSH, because glob() will run with
the simple shell as well.

Also let CONFIG_MENUTREE select on CONFIG_GLOB_SORT. While is not
strictly needed, many people use menu/00-foo menu/10-bar menu/20-barf
to sort their menu entries. So select it out of convenience.
