Flashrom fails to update ME on Intel idaville HCC platform

[Stan Jiang]

Hello developer team,

On the Intel idaville HCC platform, as long as there are differences in the
ME settings between the currently booted BIOS and the image to be updated,
the flashrom will prompt that the erase failed when updating the ME
This is the platform information I added in chip_enable.c
{ 0x8086,0x18DC, B_S, NT, "Intel", "idaville", enable_flash_c620},
The attachment is the log of the update success and update failure
Do I need to add specific settings for the Intel idaville HCC platform to
update the BIOS (ME settings are different)?
Thanks.

An example of a failed update below:
[root@localhost home]# ./flashrom -p internal:boardenable=force -w
CB2.1.01.04.bi
flashrom unknown on Linux 4.18.0-240.el8.x86_64 (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).
No DMI table found.
Found chipset "Intel idaville".
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 [e-mail] including a verbose
(-V) log.
Thank you!

OK.

Uh oh. Erase/write failed. Checking if anything has changed.

Good, writing to the flash chip apparently didn't do anything.
This means we have to add special support for your board, programmer or
flash
chip. Please report this to the mailing list at [e-mail] or on
IRC (see https://www.flashrom.org/Contact for details), thanks!
