* Moves non-DRAM early init code out of initram and into stage1, where it should have been in the first place * Fixes an issue with GP3 timer causing system reboot (possibly not present in current svn, but was present in my local copy) * Fixes serial garbage from stage1 on jetway j7f2 * Fixes ROM mapping for flash > 512k on vt8237 * Makes a couple minor whitespace changes * Moves some function prototypes to the headers where they belong * Nukes some phase2 hackery that belongs in phase4 (eventually) * Comments out early_mtrr_init() for via/epia-cn, this breaks booting on jetway j7f2 * Moves troublesome SATA init code into stage1 - change of device class hangs coreboot * Gets to vt8237 IDE phase6 init and dies on jetway/j7f2: Phase 6: Initializing devices... Phase 6: Root Device init. Phase 6: PCI: 00:10.1 init.
