flashrom

I am working on adding support for chip Winbond W25Q512JV-FIM, which should be quite similar to existing W25Q512JV. Writing to the chip is a problem, reading is fine.

$ ./flashrom -p dediprog -w random.bin 
flashrom 1.4.0-devel (git:v1.2-1310-g1ee04cd5) on Linux 6.3.9-arch1-1 (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Using dediprog id SF000000.
Found Generic flash chip "unknown SPI chip (REMS)" (0 kB, SPI) on dediprog.
