Hi Miquel,

Right now I have no idea of what happens, but you might want to add a
dump_stack() at the "Timeout waiting for RB signal" error to see what
path in the driver failed.
I've triggered it several times now, and all traces show
marvell_nfc_hw_ecc_hmg_write_page() as a stack parent.
So it seems to affect the writing routines only.
Any idea yet?
Thanks,
Daniel
