2013-05-22intel/gm45: Fix interpretation of VT-d disable bitNico Huber
When configuring the GTT size for the integrated graphics, the state of VT-d was read wrong. Bit 48 of CAPID0 (D0F0) is set when VT-d is _disabled_. In the log of a VT-d enabled roda/rk9 we have now: [...] VT-d enabled [...] IGD decoded, subtracting 32M UMA and 4M GTT [...] Without this patch, only 2M GTT were reported.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2012-11-27intel/gm45: new northbridgePatrick Georgi
The code supports DDR3 boards only. RAM init for DDR2 is sufficiently different that it requires separate code, and we have no boards to test that.
