commit 34a956739d295de6010cdaafeed698ccbba87ea4 upstream. E.g. ESMT chips will return an identification code with a length of 5 bytes. In order to prevent ambiguity, flash chips would actually need to return IDs that are up to 17 or more bytes long due to JEDEC's continuation scheme. I understand that if a manufacturer ID is located in bank N of JEDEC's database (there are currently 16 banks), N - 1 continuation codes (7Fh) need to be added to the identification code (comprising of manufacturer ID and device ID). However, most flash chip manufacturers don't seem to implement this (correctly).
