[U-Boot] [PATCH 05/30] Blackfin: bfin_mac: force boards to setup the MAC themselves

Mike Frysinger vapier at gentoo.org
Tue Feb 17 06:10:26 CET 2009


Since the on-chip MAC does not have an eeprom or similar interface, force
all Blackfin boards that use this driver to setup the board data with a
proper MAC.
