New Revision: 738
Modified:
trunk/flashchips.c
trunk/flashchips.h
Log:
Add comments about the meaning of block erase related struct flashchip
members.
Cosmetics: Place curly brackets on a common line.
Add MX25V512 as alias name to MX25L512.
Add MX25V8005 as alias name to MX25L8005.
Add erase block definitions for
MX25L2005, MX25L4005, MX25L8005, MX25L1605
and change their status to TEST_OK_PRW where applicable.
