Fsp_broadwell_de do not implement the SMI support, but you may refer to soc/Broadwell as both are Intel architecture chipset.  The SMI support can be done purely in coreboot, but need to touch FSP.

Subject: [coreboot] SMI handler for fsp_broadwell_de

I want to experiment with an SMI handler on the Camelback Mountain CRB (Xeon D-1500) but it appears that the fsp_broadwell_de changes removed SMM support.  I'm browsing the coreboot-4.4 release.  Was there a reason it was removed?  It shows up in the soc/intel/Broadwell area so I suppose I could port over the original code.  I didn't see that the D_LCK bit was set anywhere so does that mean I can potentially let SeaBIOS install an SMI handler?  Or is it set in the FSP?  I also noticed the mainline has some new code under coreboot/src/soc/intel/sch but I'm not sure which processors that is for.
