[U-Boot] UBI issues on SAMA5D31 NOR flash

I can't find the references in Patchman but they were sent to the mailing
list on 18th July 2014 in a series called "ARM: atmel: sama5d3xek: enable
NOR flash support".  The patches basically just add the board features to
enable the IO pins for the NOR flash and to map it into the memory map at
0x10000000.

Adding:

#define DEBUG
#define CONFIG_MTD_UBI_DEBUG
#define CONFIG_MTD_UBI_DEBUG_MSG
#define CONFIG_UBIFS_FS_DEBUG

Gives the following output:

I haven't booted to Linux yet.  If I try to boot with the kernel that is in
the NOR flash then I get the following output from the console messages:

0.nor_flash: Found 1 x16 devices at 0x0 in 16-bit bank. Manufacturer ID
0x000089 Chip ID 0x00899a

cfi_cmdset_0001: Erase suspend on write enabled
UBI error: ubi_init: UBI error: cannot initialize UBI, error -19

Is there something that I need to do in order to tell U-Boot and the kernel
that the base address of the NOR flash device is 0x10000000 rather than 0x0?

Thanks,

Andy.
