Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found chipset "Intel H170".
This chipset is marked as untested. If you are using an up-to-date version
of flashrom *and* were (not) able to successfully update your firmware with it,
then please email a report to flashrom@flashrom.org including a verbose (-V) log.
Thank you!
Enabling flash write... Warning: BIOS region SMM protection is enabled!
Warning: Setting Bios Control at 0xdc from 0xaa to 0x89 failed.
New value is 0xaa.
SPI Configuration is locked down.
FREG0: Flash Descriptor region (0x00000000-0x00000fff) is read-only.
FREG2: Management Engine region (0x00003000-0x0027ffff) 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.
Enabling hardware sequencing because some important opcode is locked.
