- Further work on ScsiPortInitialize(): old PortConfig section is deleted.
- SpiGetPciData() code improved, part of the code is transferred into a new function. Right now a crash is introduced in ScsiPortFreeDeviceBase(), because of the changes in ScsiPortInitialize(): will be fixed by the next commit. svn path=/trunk/; revision=26211
