You have to modify the calls to programmer_map_flash_region() in map_flash_registers() and in probe_flash(). 0xffffffff has to be changed to the last byte of the address space of your secondary flash chip.
It works perfectly! Now, I can read/write every FWH devices connected to LPC bus.
That's it. I plan to write a patch which allows you to set that stuff from the command line (-p internal:flashtop=0xffefffff), but that may not happen before end of March.
I am going to add this kind of option, because I need to have this possibility in my current project. When I do it, I will post my result here (I suppose that it will not be written in flashrom coding style, but I don't have enough time to get familiarize with it).
Thank you for help!
