Author: myles Date: Thu Apr 8 17:02:39 2010 New Revision: 5379 URL: https://tracker.coreboot.org/trac/coreboot/changeset/5379
Log: Move Kconfig for HT limits to northbridge/amd/Kconfig.
Guard the code with CONFIG_EXPERT to remove warnings.
Make it only show up for fam10, since it isn't implemented for K8 yet.
