Handle RS690 quirks for 1 GHz noncoherent HyperTransport.
The RS690 chipset has a problem where it will not work with 1 GHz HT speed unless NB_CFG_Q_F1000_800 bit 0 is set. Tested, works on my Asus M2A-VM with an 1 GHz HT capable processor. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Bao, Zheng says: As a matter of fact, both 600Mhz and 1Ghz have their own specific setting. This patch has been tested on dbm690t which HT link works on 800Mhz. Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3839 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
