Add support for the Eon EN29LV640B chip
This chip needs special command sequences in 8 bit mode. Also, 8 bit programming needs actually 16bit double byte program. The chip is found on the Bifferos Bifferboard, for example. Corresponding to flashrom svn r1521. Signed-off-by: Rudolf Marek <r.marek@assembler.cz> Acked-by: Uwe Hermann <uwe@hermann-uwe.de>
