Agreed. That would be simpler, and avoid a situation where someone relies
on the /revision property in DT to be set from the atags compat code
(preventing an upgrade to a newer bootloader), or on the system_rev variable
to be the same across multiple boot loaders, in the absence of other
kernel code setting it.
