All FSP spec v1.0 complaint FSP binary uses struct fspinit_rtbuf as defined by the 1.0 spec, however there are FSPs that do not follow 1.0 spec, like Intel FSP for 3rd generation Intel Core and Intel Celeron processors with mobile Intel HM76 and QM77 chipsets platform (formerly Chief River Platform: Ivy Bridge and Panther Point). Although Intel website says this FSP conforms to FSP v1.0 specification which defines the UPD usage, it is not really the case. This might possible due to that FSP predates the 1.0 spec. Also future FSP binary that is complaint to v1.1 spec defines an optional paltform-specific runtime data in the struct fspinit_rtbuf.
Besides this fspinit_rtbuf, the IvyBridge FSP does not support UPD either, so that current codes in arch/x86/lib/fsp/fsp_support.c won't work for that FSP. We need some flexibility, hence move those platform-specific config to chipset directory.
Right now we still use hardcoded 'const struct' table (in flash) to pass the Azalia (Intel HD Audio) verb table to FSP, because different FSP may use different verb table format (at least for Queensbay and BayTrail), we cannot handle this in the common FSP support codes. But with this series, we are now able to get Azalia verb table from device tree, just like what we did for overriding UPD data configuration. This can be done in future patch set.
Changes in v2: - Include a common struct fsp_cfg_common in the struct fsp_config_data. - New patch to introduce CONFIG_FSP_USE_UPD Kconfig option - split this patch from v1 patch#7
