Ok, it does compile.
I still have problems like oops when accessing MTD (same than before).
error is "Unhandled fault: imprecise external abort (0xcf6) at
0x20800014", which seems a blur.
I cant understand why Xscale complains, but I saw this issue has been
addressed some times on arm-linux ML, without fix (at least not in same
threads)

PXA boots of it and its BOOT_SEL is configured to "Asynchronous 16bit
ROM", elsewhere, in mem controller, it is configured as "16bit fast
flash or rom, non burst read". so I assume it is.

I can see some NAND_BUSWIDTH_16 options, but how can this be enabled at
probe time ?
