Hello, I'd like to integrate a QSPI MTD driver for the MT25QU256 Nor Flash on Freedom-K28F board. Since the Kinetis QSPI module features memory mapping of the flash and XIP, it works using a lookup table, and therefore the driver will be very architecture specific. Where should I place the files? - Clock initialization into "board". - Common Kinetis-QSPI specific functions into "chip". So far so good. But where should I place the Flash specific MTD driver? Because of the Sequence LUT, it will only work with Kinetis (perhaps with i.MX RT, I think there are similarities). As it will look strange to have a mt25kinetis.c in "drivers/mtd", should I put it into "drivers/mtd", into "chip" or into "board"? Any suggestions?
Regards, Johannes
