[PATCH V2] u-boot-fw-utils: Add support for libubootenv

[Stefano Babic]

libubootenv is a replacement for u-boot-fw-utils. It is
hardware-independent and provides fw_printenv and fw_setenv tools that
are full compatible with the ones provided by U-Boot. A library is
provided to access the environment from an own application.
License is LGPL-2.1 and this allow to link the library to proprietary
code. The user of the tools should install the configuration file
"fw_env.config", as he is already used to with u-boot-fw-utils. The
configuration file is compatible with u-boot-fw-utils.

I *really* dislike bb/inc splits where there's nothing gained apart from 
more work when editing recipes.  Can you just merge these?

Why do we need two implementations of the same in OE-core?
meta-oe sounds more appropriate to me.

Of course, I'll do in V3.

Well, it looks to me more consistent that tools for U-Boot's environment
are grouped together. It seems to me more easy and transparent. I agree
with you if u-boot-fw-utils was in meta-oe/recipes-bsp.

Best regards,
Stefano
