Maybe we want to add support for explicit EC types and reference those
here? And then have the acpi code shared between all those ECs.
The Roda RK886EX has it's EC code spread out into src/superio/renesas,
too.

shouldn't the EC makefile in src/ec/acpi say 

smm-$(CONFIG_HAVE_SMI_HANDLER) += ec.c instead?

what's the device pnp and io 0x60/io 0x62 used for? this does not look
