Block eraser conversions and support for Eon EN25B series
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.
Corresponding to flashrom svn r871.
