This patch aims to restructure SPI flash support in a more reasonable way
It introduces a generic SPI host driver for the IT8716F Super I/O
which will enable easy SPI programming without having to care for the
peculiarities of the SPI host.
To activate probing for the IT8716F, you have to use the gigabyte:m57sli
mainboard override. SPI support will then use the gathered SPI host data
to access the SPI flash.
This has been tested sucessfully by Ward Vandewege <ward@gnu.org> on the
GA-M57SLI v2.0, which has a MX25L4005 SPI flash part.
Corresponding to flashrom svn r140 and coreboot v2 svn r2817.
