This v11 patch adds support for the Microchip PCIe PolarFire PCIe
controller when configured in host (Root Complex) mode.
Updates since v10:
* Adjusted driver as per Rob Herring's comments, notably:
- use common PCI_MSI_FLAGS defines
- reduce storage of unnecessary vars in mc_pcie struct
- switched to read/write relaxed variants
- extended lock in msi_domain_alloc routine
- improved 32bit safety, switched from find_first_bit() to ilog2()
- removed unnecessary twiddle of eCAM config space
Updates since v9:
* Adjusted commit logs
* make dt_bindings_check passes
Updates since v8:
* Refactored as per Rob Herring's comments:
- bindings in schema format
- Adjusted licence to GPLv2.0
- Refactored access to config space between driver and common eCAM code
- Adopted pci_host_probe()
- Miscellanous other improvements
Updates since v7:
* Build for 64bit RISCV architecture only
Updates since v6:
* Refactored to use common eCAM driver
* Updated to CONFIG_PCIE_MICROCHIP_HOST etc
* Formatting improvements
* Removed code for selection between bridge 0 and 1
Updates since v5:
* Fixed Kconfig typo noted by Randy Dunlap
* Updated with comments from Bjorn Helgaas
Updates since v4:
* Fix compile issues.
Updates since v3:
* Update all references to Microsemi to Microchip
* Separate MSI functionality from legacy PCIe interrupt handling functionality
Updates since v2:
* Split out DT bindings and Vendor ID updates into their own patch
from PCIe driver.
* Updated Change Log
Updates since v1:
* Incorporate feedback from Bjorn Helgaas
