Seen like some issue on my dts or fdt_get_patch (lib/libfdt/fdt_ro.c)
it is returning FDT_ERR_BADSTRUCTURE
U-Boot> dm tree
simple_bus [ + ] `-- aips-bus@02100000
eth [ + ] |-- FEC
mmc [ + ] |-- usdhc@02190000
i2c [ ] |-- i2c@021a0000
i2c [ ] |-- i2c@021a4000
i2c [ ] `-- i2c@021a8000
So when I uncomment the "phy-mode" on the dts file  I was able to
get the proper i2c addr.
Couldn't find why the phy-mode node as a corrupt block based on
comment from include/libfdt.h about FDT_ERR_BADSTRUCTURE.
Simon, any help?
