Subject: powerpc/b4860qds: add xfi support
X-Git-Tag: v2015.01-rc3~1^2~19
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=89b94d851d683308e731e3ceae1a12f616d1f2f7;p=u-boot

powerpc/b4860qds: add xfi support

We need following changes to make xfi work on B4:
1. set cross-point switch VSC3308 to use sfp config when running xfi;
2. add 10G interface check for xfi;
3. set phy address for xfi so the 10G ports can be registered by mdio;
