commit c0015de92dd4165d7fe342130079da028692e76f Author: Vladimir Serbinenko phcoder@gmail.com Date: Wed Nov 19 19:59:56 2014 +0100
i945: Merge romstage main().
main() is pretty similar on all i945 boards.
Main differences after this change: * mobo supplies standard hooks to do one thing at specific romstage point * instead of supplying a SPD map mainboard supplies an SPD retrieval function with standard library function to get SPD from one EEPROM. This allows to support machines like Acer Aspire One which have no EEPROM for soldered RAM. * PCI reset is controlled by Kconfig * Artec dongle init is controlled by Kconfig. Probably should be always done but I have no hardware to test.
