From 7b6e7ba8e81a862e20d213d90aa5ba1e5a02aba6 Mon Sep 17 00:00:00 2001 From: David Daney Date: Fri, 4 Mar 2016 14:31:48 -0800 Subject: 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.
