This works perfectly now with dediprog + MX66L51235F!
Before I had the error:
$ flashrom -p dediprog -r test.bios
flashrom v1.1-rc1-12-ga724602-dirty on Linux 4.19.37-2rodete1-amd64 (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).
