This patch gives us arbitrary range reads at byte boundaries for every
single chip supported by flashrom.
That means you can tell flashrom to read exactly bytes 12345-56789
(start 12345, length 44445) and it will not fetch a single byte more.
Uwe tested this on one LPC, one SPI, and one parallel flash board.
