This patchset adds support for the PCI Express port present on
the i.MX6 SoC. The port is based on Synopsis Designware IP with
a custom PHY.
Changes since v4:
- Add an abort exception handler
- Fix register ordering in imx6q-iomuxc-gpr.h
- Enable sata_ref_100m during clock initialization
- Minor changes to lvds[12]_gate definitions
Changes since v3:
- Moved clock initialization to board clock file
- Reworked memory range layout
- Reduced the duration of several sleep calls
Changes since v2:
- Reworked source file with Sascha Hauer's suggestions
Changes since v1:
- Use the Designware controller code for BAR initialization
