[U-Boot] UBI on NAND flash again

I know there has been some traffic regaring the UBI layer recently,
however, reading the conversations didn't solve the issue I'm facing.

With a current U-Boot (git as of today) and 128MB NAND flash on a
PXA303, I get the following:

$ mtdparts

device nand0 <nand0>, # parts = 5
#: name size offset mask_flags
0: u-boot 0x00080000 0x00000000 0
1: env 0x00020000 0x00080000 0
2: splash 0x00060000 0x000a0000 0
3: kernel 0x00300000 0x00100000 0
4: ubilayer 0x07c00000 0x00400000 0

active partition: nand0,0 - (u-boot) 0x00080000 @ 0x00000000

defaults:
mtdids : nand0=nand0
mtdparts: mtdparts=nand0:512k(u-boot),128k(env),384k(splash),3M(kernel),-(ubilayer)
$ ubi part ubilayer
Creating 1 MTD partitions on "nand0":

UBI error: ubi_init: cannot attach mtd1
UBI error: ubi_init: UBI error: cannot initialize UBI, error -12
UBI init error -12

What puzzles me is this 'UBI: attaching mtd1 to ubi0' - shouldn't that
be 'mtd4'?

The same layout works well under Linux, btw.

Any hints?
