[U-Boot] [PATCH 18/30] cpu/: get mac address from environment
Mike Frysinger
vapier at gentoo.org
Tue Feb 17 06:10:39 CET 2009
The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
The cpus that get converted here:
at91rm9200
mpc512x
mpc5xxx
mpc8260
mpc8xx
ppc4xx
