Thanks Ward!

This confirms my suspicion that the IT8716F is indeed used for
LPC-to-SPI translation.

LDN 0x0, reg 0x24: val=0x1a
  serial flash interface at pin 29
  LPC write to serial flash enabled
  512kByte of flash are mapped at top of 4GByte
  128kByte of flash are mapped at top of 1MByte
  (1152kByte can be mapped at most)

LDN 0x7, reg 0x64/0x65: val=0x08/0x20
  serial flash interface base addr 0x0820 (that's an I/O port)

I have an idea what to do next, see my other mail in this thread.
