A real 970 CPU starts up with HIOR=0xfff00000 and triggers a reset
exception, basically ending up at IP 0xfff001000.
Later on this HIOR has to be set to 0 by the firmware in order to
enable the OS to handle interrupts on its own.
This patch maps HIOR to exec_prefix, which does the same thing
internally in qemu already.
It replaces the previous patch that changed the 970 initialization
constants, as this is the clean solution to the same problem.
