Super IO: NSC PC97338

[Sean Nelson]

Hi,

I have a Sony VAIO Laptop, PCG-F680K. It has a P3-700, 440BX, PIIX4,
and the titled Super IO. The main problem I'm finding from supporting
coreboot on the laptop is the SuperIO doesn't use Plug-and-Play LDNs.
What is the suggested course of action for writing support?

The Super IO controls Power Up/Down of the chip, Floppy, Serial, and
Parallel Port. It does have some PnP support for IRQs and DMA.

PS. I've spent a few days playing around with coreboot and the
registers for the PC97338.
