RAC6182-Specific Extensions to the CE API 4–25
Publication 6182-UM002B-EN-P
Portability
The argument to this function is specific to the RAC6182 hardware.
This code assumes a simple device with one memory address space size
4K configured at PCI configuration offset 0x10 and one IO address space
size 16K configured at PCI configuration offset 0x14. It has a power
management register at offset 0x40 that must be set to bring the device
out of power down mode. The device periodically interrupts us to print
data or tell us it has died.
