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.

Thanks,
-Bob
