Subject: Remove fixed host bridge check in rombios.
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=5d18e3114449aa59dc6f51aeed491ca270bc2083;p=xenclient%2Fxen-pq.git

Remove fixed host bridge check in rombios.

As we partially pass through some host GMCH pci registers when display pass-though is enabled, we can't assume we are using fixed host bridge.
