I assume this is an hardware configuration.
Would it be possible to change 16bit access to 32bit in MTD chip while
running?

I tried to reconfigure PXA bank mode to 32 bit mode: probing no more
works, and mmio transfers dont crash any more...
So if I understood well, PXA just makes kernel crash if accessing a
16bit mapped zone with 32bits words (quite normal, in fact, but not
straightforward for me as I'm learning at the same time ;)

As I saw different bug reports/issues on MLs with this kind of thing
(PXA kernel crashing while probing mtd), shouldn't a #warning, or a
printk just before probing annoucing the issue could be added ?

Cheers !
