The Synopsys Designware IP is shared with couples of platforms under multiple architectures. The series of patches is to provide basic architecture-independent Designware PCIe host driver including ATU initialization and PCI OPS. Currently, which supports arm and arm64 simultaneously. I do not directly add arm64 support to pcie-designware.c, the main reason is that it is hard to port other 5 platform PCIe driver based on pcie-designware to the new implementation. However, not changing those PCIe driver means the code for arm32 must be remained. I add a new file pcie-designware-base.c. Compared with pcie-designware.c, there are main 3 differences. 1. It is a new implementation followed the latest PCIe architecture-independent API without any code for specific architecture. 2. There is no MSI chip code, which will be implemented in a separated file. 3. Improve ATU use - support more than 2 ATUs and use an exclusive ATU to translate MEM transaction.
