Hi Miquel,

So I just tested right now, and good news, it now works pretty fine
here, and my jffs2 properly mounted (without requiring Boris' fix
for oob) :

# dmesg|grep -i nand
[    0.770395] nand: device found, Manufacturer ID: 0x01, Chip ID: 0xf1

[    3.245034] jffs2: version 2.2. (NAND) (SUMMARY)  \xffffffc2\xffffffa9 2001-2006 Red Hat, Inc.

I was first surprized seeing this "pxa3xx_nand-0" still appearing until I
realized that it's how it's called in the device tree :-)

Cheers,
Willy
