[ Upstream commit 574f29036fce385e28617547955dd6911d375025 ]

Previously quirk_paxc_bridge() was applied when the iproc driver was
built-in, but not when it was compiled as a module.

This happened because it was under #ifdef CONFIG_PCIE_IPROC_PLATFORM:
PCIE_IPROC_PLATFORM=y causes CONFIG_PCIE_IPROC_PLATFORM to be defined, but
PCIE_IPROC_PLATFORM=m causes CONFIG_PCIE_IPROC_PLATFORM_MODULE to be
defined.

Move quirk_paxc_bridge() to pcie-iproc.c and drop the #ifdef so the quirk
is always applied, whether iproc is built-in or a module.

[bhelgaas: commit log, move to pcie-iproc.c, not pcie-iproc-platform.c]

PCI: tegra: Fix afi_pex2_ctrl reg offset for Tegra30 2020-02-14T21:52:57+00:00 Marcel Ziswiler marcel@ziswiler.com 2020-01-07T08:14:02+00:00 df6852e3b569c1ce69113457d24b7ad2f1fd6a6b commit 21a92676e1fe292acb077b13106b08c22ed36b14 upstream. Fix AFI_PEX2_CTRL reg offset for Tegra30 by moving it from the Tegra20 SoC struct where it erroneously got added.

The Keystone outbound Address Translation Unit (ATU) maps PCI MMIO space in 8 MB windows. When programming the ATU windows, we previously incremented the starting address by 8, not 8 MB, so all the windows were mapped to the first 8 MB. Therefore, only 8 MB of MMIO space was accessible. Update the loop so it increments the starting address by 8 MB, not 8, so more MMIO space is accessible.
