Add SPI flash emulation capability to the dummy programmer.
You have to choose between
- no emulation
- ST M25P10.RES SPI flash chip (RES, page write)
- SST SST25VF040.REMS SPI flash chip (REMS, byte write)
- SST SST25VF032B SPI flash chip (RDID, AAI write)
Example usage: flashrom -p dummy:emulate=SST25VF032B
Flash image persistence is available as well.
Example usage: flashrom -p dummy:image=dummy_simulator.rom
Allow setting the max chunksize for page write with the dummy
programmer.
Example usage: flashrom -p dummy:spi_write_256_chunksize=5
Flash emulation is compiled in by default.
This code helped me find and fix various bugs in the SPI write code
as well as in the testsuite.
