Changes since v1: -Improved commit message in patch 3/3. -Picked up tags. Kind regards, Niklas
Hello all, This series adds some extra checks to ensure that it is not possible to program the iATU with an address which we did not intend to use. If these checks were in place when testing some of the earlier revisions of Frank's doorbell patches (which did not handle fixed BARs properly), we would gotten an error, rather than silently using an address which we did not intend to use. Having these checks in place will hopefully avoid similar debugging in the future. Kind regards, Niklas Niklas Cassel (3): PCI: artpec6: Implement dw_pcie_ep operation get_features PCI: endpoint: Add size check for fixed size BARs in pci_epc_set_bar() PCI: dwc: ep: Add 'address' alignment to 'size' check in dw_pcie_prog_ep_inbound_atu() drivers/pci/controller/dwc/pcie-artpec6.c | 13 +++++++++++++ drivers/pci/controller/dwc/pcie-designware-ep.c | 8 +++++--- drivers/pci/controller/dwc/pcie-designware.c | 5 +++-- drivers/pci/controller/dwc/pcie-designware.h | 2 +- drivers/pci/endpoint/pci-epc-core.c | 11 +++++++++-- 5 files changed, 31 insertions(+), 8 deletions(-)
