[ELDK] AMCC Kilauea and Xenomai : IP-Config 'eth0' not found

[Tim Cussins]

Hi Jonathan,

Before I push on, I should mention that I've patched 2.6.30.3 with
xenomai 2.5.0 and things are now working fine :)

I hear ya about the configuration. I have definitely been making
kilauea_defconfig - it looks like networking isn't enabled in this
config (for powerpc).

I diffed the kilauea configs from ppc and powerpc - the powerpc
(required to build xenomai) config is missing a few suspicious bits:

-CONFIG_NET_ETHERNET=y
-CONFIG_MII=y
-CONFIG_IBM_EMAC=y
-CONFIG_IBM_EMAC_RXB=256
-CONFIG_IBM_EMAC_TXB=256
-CONFIG_IBM_EMAC_POLL_WEIGHT=32
-CONFIG_IBM_EMAC_RX_COPY_THRESHOLD=256
-CONFIG_IBM_EMAC_RX_SKB_HEADROOM=0
-CONFIG_IBM_EMAC_PHY_RX_CLK_FIX=y
-CONFIG_IBM_EMAC_RGMII=y
-CONFIG_IBM_EMAC_NR_START=0
-CONFIG_INPUT=y

I could look into this more, but I've got a newer kernel, latest
xenomai, all working: I think I'll run with that for now.

Cheers,

Tim
