[U-Boot] UBI issues on SAMA5D31 NOR flash

[Andy Pont]

Hello,

Using the patches from Bo Shen to support the NOR flash on the Atmel
SAMA5D31EK hardware platform I am trying to get a UBI root file system
within the NOR flash, at offset 0x10000000 in the memory map, to work but
get errors from the "ubi part" command using U-Boot 2014.04:

U-Boot> mtdparts

device nor0 <physmap-flash.0>, # parts = 5
 #: name                size            offset          mask_flags

Any ideas as to what I have missed?

Thanks,
