SubjectRe: [PATCH] platform/chrome: cros_ec_lpc: Add DMI definition for post-Skylake machines running custom Coreboot builds
From
Thank you for your feedback.

I've explained the reason behind adding this patch, but we'll go with
different approach next time around.

Since we're discussing this, I would like to suggest removal of DMI
matches for EOL machines from lines 503...535 (Link, Samus, Peppy, Glimmer).

Those machines aren't supported by Google anymore. Patch I suggested
will match DMI while running custom firmware.

If maintainers are okay with it, I will submit a patch removing DMI
matches for stock firmware running on those machines since it's not
needed anymore.
