Re: [PATCH v5 2/3] platform/chrome: cros_ec_lpc: Add support for Google Glimmer

[Gwendal Grignou]

This is not required.
Looking with dmidecode, Glimmer reports:
...
BIOS Information
        Vendor: coreboot
        Version: Google_Glimmer.5216.198.19
...

Therefore, the first entry of cros_ec_lpc_dmi_table will match.
