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 ...

CPU_ARM946E is selected by boards, so letting it depend on !MMU
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:
warning: (BLSPEC && DEFAULT_ENVIRONMENT_GENERIC_NEW) selects FLEXIBLE_BOOTARGS
which has unmet direct dependencies (COMMAND_SUPPORT && CMD_GLOBAL)

blspec: fix incompatible pointer type warning ...

The warning is correct in that we pass in size_t instead
of int. As we are not interested in the size of the
property at this point, just remove the assignment.

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.

globalvar: Add support for printing all global variables ...

This could previously only be done with 'devinfo global'. While
this is still possible this adds a more direct access via the
globalvar command. This variant also adds a '*' in front of
the variable if the corresponding non volatile variable exists.

Add support for non volatile variables ...

This adds (back) support for non volatile variables. Non volatile
variables are variables which are stored in the environment over
reboot. They are used in the same way as the global variables, but
with a 'nv' command and device. The variables are stored under
/env/nv/, one variable per file. Adding a nv variable automatically
adds a global variable with the same name. Changing a nv variable
also changes the same global variable, but not the other way round.
This allows for example to configure the username as:

nv user=sha; saveenv

common: fix mbr filetype detection ...

Sometimes mbr is erroneously recocognised as FAT partion. Due to this the mbr
partition parser is not being called and the partitions on the media are not
detected. This patch should  fix the problem. The checking is done as in the
linux kernel.

I have seen the problem using usb sticks. Although partitioning and formatting
them under linux. The file system type field in the mbr remains there which
causes the wrong detections as FAT32 type and not as mbr.

dev_add_param creates a new parameter so it makes more sense to

is hardly ever checked this is only a small patch.

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.
