This series tries to clean up the handling of the configuration files which are
required by the libubootenv.
Further patches (going to meta-yocto-bsp) will provide a complete example for
the beaglebone-yocto machine which just works with OE-core and meta-yocto-bsp.

Without /etc/fw_env.config, the fw_printenv and fw_setenv utilities fail
with an error, as they cannot locate the U-Boot environment.
This limitation also affects any application linking against
libubootenv. To address this, add an RRECOMMENDS from libubootenv to the
u-boot-env package, which provides the necessary configuration files.
While this could be an RDEPENDS, using RRECOMMENDS allows users with
custom implementations to more easily override the dependency if needed.
Some examples suggest bbappending fw_env.config directly to the
libubootenv recipe. However, /etc/fw_env.config is machine-specific,
whereas libubootenv is not. Additionally, the default U-Boot
environment, which can be used by libubootenv, is also provided by the
machine-specific u-boot-env package. Therefore, it is preferable to
provide fw_env.config via the machine-specific u-boot recipe.

Usually the debug symbols are split into a libubootenv-dbg package.
Dropping them already at compile time is not needed and causes problems
when debugging libubootenv.

I fear this is not enough because it has a side effect. MAKE_BUILD_TYPE
is set here not to drop the debug files, but to avoid debug output.
Cmake sets automatically NDEBUG if CMAKE_BUILD_TYPE=Release, and this is
the goal of the EXTRA_OECMAKE because NDEBUG is used in code. The change
here will break user's scripts.
Regards,
Stefano

Hi,
I think this patch produces the following warnings:
stdio: WARNING: Nothing RPROVIDES 'u-boot-env-native' (but virtual:native:/srv/pokybuild/yocto-worker/a-full/build/meta/recipes-bsp/u-boot/libubootenv_0.3.6.bb RDEPENDS on or otherwise requires it)
stdio: WARNING: Nothing RPROVIDES 'libubootenv-native' (but virtual:native:/srv/pokybuild/yocto-worker/a-full/build/meta/recipes-bsp/u-boot/libubootenv_0.3.6.bb RDEPENDS on or otherwise requires it)
stdio: WARNING: Nothing RPROVIDES 'libubootenv-dev-native' (but virtual:native:/srv/pokybuild/yocto-worker/a-full/build/meta/recipes-bsp/u-boot/libubootenv_0.3.6.bb RDEPENDS on or otherwise requires it)
Happens on `bitbake universe -c fetch -k`.
Can you have a look?
