Author: mcayland Date: Sun Jan 2 01:07:19 2011 New Revision: 1008 URL: http://tracker.coreboot.org/trac/openbios/changeset/1008
Log: Switch all SPARC32 devices over from the private map_io() function over to OFMEM's ofmem_map_io() function.
The old map_io() function can now be removed. Also fill in ofmem_arch_early_map_pages() on SPARC32 which is required for ofmem_map_io() to work correctly.
