commit 6935d3aad1075397248477a6c16ed0a2d7d80947 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Mon Feb 3 17:04:22 2014 +0200
console: Drop driver list in ramstage
This framework was only available in ramstage. So we had to define console output functions separately for bootblock, romstage and SMM. Follow-up patches will re-enable all the consoles removed here, in a more flexible fashion, and with less lines-of-code and copy-paste.
Also the driver list is not in a well-defined order and some of the loops could exit without visiting all drivers.
NOTE: This build has no console in ramstage.
