ADI BF DSP PCI接口代码

PCI example for the Eagle-35 and Hawk-35 boards.
The Eagle-35 board has the ADSP-BF535 processor as the PCI system Host
and the Hawk-35 board has the ADSP-BF535 processor as a PCI Device.
In this example the host initializes itself for PCI Host operation and then configures the device.  
It is important to note that the device should have its PCI configuration space initialized
and enabled before the host can attempt to configure the device.
After configuring the device the host then sends via MemDMA a blink program to the device. 
The host then sends a token (0xFEED FACE) to the device's PCI_CBAP register which the device can poll
and then jump to the base of L2 (0xF000 0000) to begin execution of the transferred program. 
Or, alternatively, one may just reset the device's program counter to 0xF000 0000 and run the program.
