In order to build BSPs that were not already integrated into
the upstream linux yocto kernel AND keep the git fetcher happy,
some fairly complex anonymous python sections were required.
These sections cause problems with variable expansion and SRCREV
processing.
With the updated git fetcher code, we can streamline the BSP
boostrapping process and drop 99% of the anonymous python code.
This commit has the following changes to support BSP boot strapping
and simplication for existing BSPs.
- KMETA is set per-recipe rather than in python code
- undefined machines are no longer used, but instead common
branch names are set per-recipe
- fallback machine SRCREVs are present in the default revisions
file
- A new variable YOCTO_KERNEL_EXTERNAL_BRANCH should be set in
the local.conf for new BSPs instead of being programatically
determined in the anonymous python.
- No more explicity KMACHINE variable expansion and manipulation,
since the tools and build phases no longer require it due
to the per-recipe fallbacks.
Integrated/merged BSPs are unaffected by the changes and have been
regression tested.
