Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). coreboot table found at 0x7ff4f000. Found chipset "Intel QM67". Enabling flash write... FREG0: Flash Descriptor region (0x00000000-0x00000fff) is read-only. FREG2: Management Engine region (0x00003000-0x004fffff) is locked. Not all flash regions are freely accessible by flashrom. This is most likely due to an active ME. Please see https://flashrom.org/ME for details. At least some flash regions are read protected. You have to use a flash layout and include only accessible regions. For write operations, you'll additionally need the --noverify-all switch. See manpage for more details. OK.
