Could you please give me some reference code on how to make fid change
effective on HT1000 southbridge?  Thanks!

	LDTSTOP may need to SB to help.

	 

	When trying to change cpu fid, CPU need LDTSTOP to make the FID
change effective.  enable_fid_change_on_sb will enable ldtstop on sb.

	 

	Current Amd8111 support code already have
enable_fid_change_on_sb in the public tree.

	 

	Serverworks ht1000 need to call ldtstop explicitly to make fid
change effective. I will check in the code after the new cpu is
released.

	 

	The problem the ck804 has problem with ldtstop. We have to use
some other way to make it effective...
