trunk/chipdrivers.h
trunk/flashchips.c
trunk/stm50flw0x0x.c
Log:
Convert chips to block_erasers:
SyncMOS S29C31004T
SyncMOS S29C51001T
SyncMOS S29C51002T
SyncMOS S29C51004T
TI TMS29F002RT
TI TMS29F002RB
SyncMOS chips have Uniform sector; boot blocks on chips are made up of uniform sectors but have locking.
