1.1
log
@Add support for MPC5200B SoC, including:
- BestComm DMA controller
- Clock Distribution Module
- Fast Ethernet Controller, utilizing BestComm DMA
- AC97 controller, utilizing BestComm DMA
- ATA controller (PIO-only, hardware DMA is too broken)
- On-chip SRAM (needed for BestComm)
- PSC UART (for console)
- PCI along with bus mater DMA support

All of this is based on previous work by Robert Swindells and would not
be possible if it wasn't for his effort.
