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.
