[U-Boot] NAND FDT mapping on Canyonlands

[U-Boot] NAND FDT mapping on Canyonlands

[Felix Radensky]

Hi,

Canyonlands board port has its own version of ft_board_setup(),
overriding the generic one from cpu/ppc4xx/fdt.c. Canyonlands
version is missing the code that sets OPB/PLB mappings in device
tree. As a result, Linux NAND driver is unusable on this board, as
it fails to find a relevant NAND EBC mapping.

Will a patch adding OPB/PLD mapping code to Canyonlands version
of ft_board_setup() be accepted ?

Felix.

As you state it, it fixes a real bug, so sure it will be considered ;)

I'm not too much into it, but please try to come up with a patch sharing
as much and copying as few as possible...

Cheers
