I think there is a fundamental disconnect here.  Except when
I miscompile auto.c the AMD reference board boots fine.  And in this
aspect the code is fundamentally the same as earlier revision of
LinuxBIOS.  auto.c just gets compiles into auto.inc

And I can't think of a board where I have had problems with jumping
to hardwaremain.  _RAMBASE should not strongly affect anything, it
just need to be in a location where the ram initialization code
always puts ram.  Only with respect to stack size, and the LinuxBIOS
tables should it have any issues with various locations in ram.
