I start writing PCI Express driver code for the embedded system in which master embedded board is using MPC837x to communicate with other devices using PCIe . I have no experience in such driver and do not know where to start. Anyone can provide or point me to where I can find the basic PCIe driver of this processor MPC837x or similar one? Thanks
Please refer to the U-Boot PCI driver source code and PCIe patches provided in the MPC837x MDS LTIB BSP:
