I think we should at least get it to work again. Otherwise it's pointless
to pollute the kernel. No way to get any tester if all you get when you
load it is :

  calling drivers/mtd/nand/armada_nand.c:3227 orion_nfc_probe
  armada-nand nand.3: Initialize HAL based NFC in 8bit mode with DMA Disabled using BCH 4bit ECC
  drivers/mtd/nand/armada_nand.c:3318:orion_nfc_probe irq=105
  armada-nand: probe of nand.3 failed with error -12

Oh damn, I'm back in the code again trying to fix it now...

Also we must not put it into staging in its current shape as it
patches drivers/mtd. We must first apply Ezequiel's explanation
about the READID command to detect the ONFI flash. I don't know
how long this could take. I remember having noticed this difference
in later drivers that was not there without knowing what it was
about.

What makes me uncomfortable is that we have guys who have started
some clean work and in parallel we're doing some crap which will
discourage Marvell from reprioritizing their work. I'd rather keep
that as an out of tree patch so that nobody there claims that the
NAND driver already exists in the kernel.

Best regards,
Willy
