Platform independent drivers documentation

The drivers can be found in src/drivers. They are intended for onboard and plugin devices, significantly reducing integration complexity and they allow to easily reuse existing code across platforms.

For details on how to connect device drivers to a mainboard, see Driver Devicetree Entries.

Some of the drivers currently available include:

• Intel DPTF
• IPMI KCS
• SMMSTORE
• SMMSTOREv2
• SoundWire
• USB4 Retimer
• CBFS SMBIOS hooks
