Leif,

I could see edk2-platforms/master being the platform branch that
contains the set of platforms that are synced with edk2/master and
are required to be tested when changes are made to edk2/master.
Or at least guaranteed to be tested when a stable release of 
edk2/master is made.

Similar to what we expect for the platforms in edk2/master such
as OvmfPkg, EmulatorPkg, and Nt32Pkg.

Given that not everyone would have access to platform targets to 
run tests, the minimum requirement could be build tests.

Mike
