I'm looking into cleaning up the flash db and come across the n_banks
and n_dice parameter. Which sounds like they seem to be similar, maybe
identical? Unfortunately, there is no public datasheet for the macronix
flash.. IIRC there is one for the Semperflashes but I'm not sure if
there
is one for the MCP parts.
Could we somehow clarify if these are the same properties? I've looked
at
the SFDP tables of the macronix flash and they don't have the SCCR map
for
multi chip devices :/
