Yes, that fix is fine, thanks.



I was having a cleanup of the whole SPI/LPC bus handling in mind:

we have _1_ global variable (per instance of "flashes"?) instead of one
per supported chipset.

This variable is an ENUM

enum flash_bus {
   FLASH_BUS_LPC,
   FLASH_BUS_ICH7_SPI,
   FLASH_BUS_ICH9_SPI,
   FLASH_BUS_VIA_SPI,
   FLASH_BUS_IT87_SPI
}

I think this matches the physical actualities much better than the
design-less hack that is used at the moment. Also the code could be much
nicer in many places, as we could use case statements instead of endless
if () else if () else if() statements


But even without this:
Instead of unconditionally setting ich7_detected, it should only be
conditionally set if bbs == 1 (SPI) because the flag really means
"spi_strapping_detected_on_ich7"
