Log:
- 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.
