Great! Thanks for testing.

Boris' fix wouldn't apply anyway as it was written for pxa3xx_nand.c
and here you are using marvell_nand.c and the code is really different.

That is right, but if you create a DTS for your own board feel free to
change it, this is just a default name. Giving it some meaning (like
"main-storage" or "backup-storage") is how you could use this label.

Thanks again for your help, reviews or tested-by's are welcome for this
driver ;)
