Now that the nand drivers are responsible for selecting the target prior to hardware access, a call to marvell_nfc_select_target() is necessary from marvell_nfc_setup_data_interface().
This is a regression introduced by commit b25251414f6e ("mtd: rawnand: marvell: Stop implementing ->select_chip()").

I had a short look yesterday and this is very likely to be the root cause of the regression, thank you very much!
Yes it is, it fixes the regression I have reported.
Do you want me to resend with that nit addressed you mentioned? My version works well, I know that much :)
Thanks, Daniel
