Point me to the exact place of documentation if convenient? I have
been reading(quick browsing) the ICH7 spec., but have not found this

various docs these days.

About when? Maybe I can help search for it.

BTW, I have not finished reading ichspi.c, but ask previously, are we
able to write a part of the chip in ichspi.c(to support ROM layout)?
