Patch Set 1: Code-Review+2

Patchset:
PS1: Okay so at first glance there are no side effects neither before applying the patch nor after the patch. A little bit of performance stats (debug level 7, serial port enabled):
2,818,129 usecs - no spi100 2,798,503 usecs - spi100 before patch 2,804,461 usecs - spi100 after patch
The discrepancy between SPI100 with and without patch may be a result of AGESA memory training (bad luck with seed or something). Anyway the gain from SPI100 in this case is about 15-20ms
