If this is going to be the approach, I would like to once again suggest that
paths, configuration options, and compatibility strings along the lines of
"mach-genericarmv7", "Generic ARMv7 Machine", and "linux,genericarmv7" be
considered in place of "mach-virt", "Dummy Virtual Machine" and
"linux,dummy-virt", respectively.

Virtualization may have been the initial motivation for creating mach-virt,
but the code is clearly also immediately applicable to other environments such
as simulation/emulation, and sticking to a name like "Dummy Virtual Machine"
makes it sound like such usage is erroneous.

Regards,
Christopher
