v2:
- Fix definition of XEN_VIRT_START macro which incorrectly used
_AT instead of _AC.
- Use _start instead of start
In preparation for implementing ISA3+ Radix MMU support, drop ISA 2.07B
from the supported ISA list to avoid having a non-working
configuration in tree. It can be re-added at a later point when Hash
MMU support is added.

xen
start execution at XEN_VIRT_START after the copy
since hardware will ignore the top 4 address bits when operating in Real
Mode (MMU off).

also drops support for POWER8 for now, to avoid having a

My idea was to license any file where I expect there to derivations
from existing code as GPLv2+, and fall back to GPLv2-only for
new
