Hello Hsuan Ting Chen, Subrata Banik, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/81357?usp=email
to look at the new patch set (#4).
The following approvals got outdated and were removed:
Verified-1 by build bot (Jenkins)

ichspi.c: Add support for region 9 and beyond in Meteor Lake
Since Meteor Lake, configuring region access for FREG9 and higher is
necessary. This configuration is determined using BIOS_BM registers:
BIOS_BM_RAP (Offset 0x118): BIOS Master Read Access Permissions.
Each bit [15:0] corresponds to a region [15:0].
A set bit grants BIOS master read access.
BIOS_BM_WAP (Offset 0x11c): BIOS Master Write Access Permissions.
Each bit [15:0] corresponds to a region [15:0].
A set bit grants BIOS master write/erase access.
Move CHIPSET_METEOR_LAKE to the bottom of the ich_chipset list to ensure
that all the newer chipsets in the future will use BIOS_BM check by
default.

I haven't noticed the configuration register ahah. Thanks for pointing that out, then it's fine!
P.S. I feel the same, thank you :)

PS1, Line 12: * Incorporate missing region names from https://github.com/coreboot/coreboot/blob/main/util/ifdtool/ifdtool.c for completeness.
> Thank you for syncing region names in two places! I am curious, is there any official doc from Intel […]
I believe there should be a document with its name like 'MTL SPI Programming Guide,' but I don't think it's publicly accessible. (I'm afraid I can't share anything since I don't have access myself.)
Perhaps Subrata could share some knowledge about where are those region names?
Patchset:
PS1:
Hi Subrata:
Could you share if there's any basic knowledge about how Intel introduce those region names?

> For this line (and diffs below in this file) you have changed the number of spaces between names? So […]
Yes, we used to pad names to 4 characters (lines 534 and 538). However, some newer names like '10GbE0' are too long.
To accommodate this, I now pad all names to 6 characters (with center alignment).
