From 0e138b0da002197cc86f601be5b307386a5fdfab Mon Sep 17 00:00:00 2001

Subject: Modify debug framework to be build-independent

During boot, Hostboot will push key pointers into memory.  This
allows the debug tools to find the pointers (using a known static
memory address) to base memory accesses on.  This replaces the
existing symbol lookup that we use now.  That means we don't
need to have the exact symbol file for the build we're debugging
against.
