This patch adds support for - Pm25LD256C - Pm25LD512(C) - Pm25LD010(C) - Pm25LD020(C) - Pm25LD040(C)
These seem to be the successors of the Pm25LV series. The main difference seems to be the dual I/O and additional erase opcodes. Some support an additional, complex locking register (maybe all of the above, but available datahsheets do not indicate it for all).
