Bit banging SPD code

[Peter Fox]

I would like to make the STPC elite ram initialisation use SPD info.

I notice that all the existing SDRAM initialisation that uses
SPD seems to use some kind of SPD controller. Is this true ?

The STPC elite only provides a bit banging SPD interface, has
anyone implemented smbus_read_byte etc with a bit banging interface ?

Yes.

Not for LinuxBIOS so it looks like you have some work ahead of you.
On the plus side a bit banging interface since you get more control
provides the opportunity for more robust error handling.
