[PATCH 0/2] linux-wrs: improve BSP-bootstrap process

Bruce Ashfield <bruce.ashfield@...>

I've been looking to improve the introduction of new boards
to the supported kernel for some time, and this takes us
most of the way there. Now with a machine.conf and a defconfig
you can create an initial working environment for BSP development
with no manual/workaround steps.

When creating a new BSP there isn't always an upstream branch
to validate SRCREVs against. Therefore, creating a new BSP
required extra manipulations of the git repository, even though
the branch for the build would be dynamically created.

To fix this, provide a fallback to the 'standard' branch if
WRMACHINE is not assigned a specific value for the given MACHINE.
The fallback saved in KBRANCH, and represents the branch that
we should build, even if no fallback is required. Some substeps
of the recipe have been updated to use KBRANCH rather than

There will be one additional change to not track the SRCREV
of wrs_meta as a fallback, but I wasn't able to get the
standard branch tracking working, so I'm sending this as-is
for now.

I've tested this with my kernel development layer, and with
the stock meta directories only. Either way, I was able
to build and test a 'qemumips-variant' quickly.
