New Revision: 269636
URL: http://svnweb.freebsd.org/changeset/base/269636
Log:
Set fb_pbase properly on PowerPC in the case where we have to guess at
the right register bank for the framebuffer. Disable the assigned-addresses
path on SPARC since it is just a hack for IBM PPC systems and was neither
relevant for nor worked on SPARC anyway.
