[U-Boot-Users] [PATCH 1/3] Convert mpc7448hpc2 to CONFIG_OF_LIBFDT
Jerry Van Baren

Tue Jun 3 01:55:02 CEST 2008
This was configured to use the deprecated CONFIG_OF_FLAT_TREE, change
to CONFIG_OF_LIBFDT.
WARNING: This conversion was untested because I do not have a board to
test it on.
NOTE: The FDT blob (DTS) must have an /aliases/ethernet0 and (optionally)
/aliases/ethernet1 property for the ethernet to work.
