ndfc driver on Kilauea board

Hi,

I'm trying to enable Linux ndfc driver on Kilauea (ppc405ex) board rev 1.2 running
u-boot v2009.01 and linux-2.6.29-rc3. I've enabled NDFC in kernel config and updated kilauea.dts as described in Documentation/powerpc/dts-bindings/4xx/ndfc.txt
NDFC chip select is 1, so it matches the example in ndfc.txt However driver probe routine is not called by the kernel, and NAND is not identified. What am I missing ? The same driver (backported) works for me on custom 460EX board with u-boot-1.3.4 and linux-2.6.28

Thanks a lot in advance.

Felix.

U-boot on Kilauea ships with the following definitions:

fdt_addr=0xfc1e0000
net_nfs_fdt=tftp 200000 ${bootfile};tftp ${fdt_addr} ${fdt_file};run nfsargs addip addtty;bootm 200000 - ${fdt_addr}

I was running net_nfs_fdt to download kernel and fdt from network, but in reality
fdt stored on flash was used, which has no ndfc definitions. Now that I'm using
a proper ftd, NAND is properly identified.

Sorry for the noise.

Felix.
