> Enable verbose SMBIOS table generation so that user space applications
> can use the SMBIOS table to provide details about the system. The
> desired information is chassis-type to determine whether the system is
> laptop.
> Adding the chassis-type property is proposed for the upstream device
> trees in the Linux kernel in [1].
> Enable CMD_SMBIOS as debugging aid as the platform can easily deal with
> large u-boot binaries.

> I do not plan to update u-boot's in-tree device trees. The Linux device
> trees have almost reached feature parity. The main missing features are
> the USB Type-C ports (on track for next merge window) and the laptop
> keyboards. I think it makes more sense to close the feature gap and
> switch to upstream device trees instead of adding to the in-tree device
> trees.
