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.
Corresponding to flashrom svn r596.
