PPC440GX IBM EMAC2/3 RGMII mode selection

[David Grab]

Hello,

i have some problems to configure emac2, emac3 support of my ibm ppc440gx
for linux kernel 2.6.11.6. I have two RGMII Phy´s connected to the ppc an no
other PHY´s are connected. PPC Strapping is selected for Group4 (SMII, SMII,
RGMII/RTBI, RGMII/RTBI). I only want to configure the RGMII support of emac2
and emac3. But it seems like the PHY´s are used for eth0 (emac1) and eth1
(emac2) which are configured as SMII. Could someone tell me, what i have to
configure to select only emac2 and emac3 in RGMII mode?

Thx for help,

David
