(cc'ing the sbsa-ref maintainers)
This isn't an objection, but I would like to know what the
sbsa-ref maintainers' view is on what CPUs the board type
is supposed to handle. Is this like the virt board, where we
add basically any CPU type that might possibly work? Or is
it more like a piece of 'real' hardware, where there are only
one or two CPU types that that hardware might have shipped with,
and the firmware/software stack might not be built to cope with
anything more ?
If we can answer the general question, then specific
patches like this one will be easy to review.
