Okay, I've tested this on cm-x300. The result is not bright :
nand: device found, Manufacturer ID: 0xec, Chip ID: 0xdc
nand: Samsung NAND 512MiB 3,3V 8-bit
nand: 512 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64
pxa3xx-nand pxa3xx-nand: ECC strength 1, ECC step size 512
Scanning device for bad blocks
random: nonblocking pool is initialized
Bad eraseblock 1037 at 0x0000081a0000
Creating 6 MTD partitions on "pxa3xx_nand-0":
0x000000000000-0x000000040000 : "OBM"
0x000000040000-0x000000080000 : "U-Boot"
0x000000080000-0x0000000c0000 : "Environment"
0x0000000c0000-0x000000200000 : "reserved"
0x000000200000-0x000000600000 : "kernel"
0x000000600000-0x000020000000 : "fs"
The bad black is not bad normally.
And then :
# dd if=/dev/mtd0 of=toto count=1
pxa3xx-nand pxa3xx-nand: Wait time out!!!
1+0 records in
1+0 records out
# ls -l toto

That's not possible, as it should have dumped the OBMI.
And yet, I hesitate to incriminate this patchset, I will try without it. It wont
be very fast, as my USB to serial converter just broke, and my order will take a
couple of days to complete.
And of course without this converter I cannot test anymore, especially the
zylonite board which will be more interesting.
So I'll report back as soon as the UK mail has completed the shipment.
Cheers.
