Subject: ppc4xx: Don't write the MAC address into the internal SoC registers
X-Git-Tag: v2009.06-rc1~148^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9cd690160d3ce1a7fb4ceeee6c99cedb1ac1d49c;p=platform%2Fkernel%2Fu-boot.git

ppc4xx: Don't write the MAC address into the internal SoC registers

Remove this code. It's not needed. The 4xx EMAC driver stores the MAC
addresses into the SoC registers instead.
