David Daney 7b6e7ba8e8 PCI: thunder: Add driver for ThunderX-pass{1,2} on-chip devices
The cavium,pci-thunder-ecam devices are exactly ECAM-based PCI root
complexes.  These root complexes (loosely referred to as ECAM units in the
hardware manuals) are used to access the Thunder on-chip devices.  They
are special in that all the BARs on devices behind these root complexes are
at fixed addresses.

Add a driver for these devices that synthesizes Enhanced Allocation (EA)
capability entries for each BAR.

Since this EA synthesis is needed for exactly two chip models, we can hard-
code some assumptions about the device topology and the layout of the
config space of specific DEVFNs in the driver.

Enables support for the PCIe controller in the DRA7xx SoC. There
are two instances of PCIe controller in DRA7xx. This controller can
act both as EP and RC. This reuses the Designware core.
