Ron,

Attached is the third revision of the CN400/EPIA-N(L) patch for CB V2.

Patch should work against r4381 (or later ?)

This version now boots all of the way through to attempting to launch a
payload (I'm trying FILO right now), where it falls over with exception
6 (invalid opcode)

The coreboot_table issue seems to have been automagically resolved by
the latest core files.

It may still be that the reason for the payload not starting is down to
some issue with the tables initialising, I'll look closer at that.
