[OE-core] [RFC PATCH v5 0/2] Pending changes for review/discussion

[Otavio Salvador]

I am resending those two patches as they are not fully
discussed/reviewed.

The EXTRA_DISTRO_FEATURES (1/2) one has a mix of people which likes it
and others who hates it. Personally I would like to get a mechanism
like this one supported and it allows for much easier use of
DISTRO_FEATURES during development phase. People argue it can be
abused and this is a real possibility and something that will happen
however this happens with everything so it does not justifies, for me,
the not inclusion of it.

On the other side the UBOOT_CONFIG (2/2) one is not complete in my
opinion. It needs someone to help to find the gabs so I can fix those
and propose a final patch.

Changes in v5:
- Resend

Changes in v4:
- Drop _prepend/_append hack and remove/add DISTRO_FEATURES (thanks to
  RP for the tip).

Changes in v3:
- Drop _prepend/_append flags from DISTRO_FEATURES to avoid the re-add

Changes in v2:
- Use data copy to fix wrong prepend/append expanding.

Otavio Salvador (2):
  base.bbclass: Add support to EXTRA_DISTRO_FEATURES
  uboot-config.bbclass: Allow choose of U-Boot config for machine
