[U-Boot] [PATCH v4 0/23] ARM: tegra: Add PCIe support

[Simon Glass]

From: Thierry Reding <treding at nvidia.com>

(Commit message updated by Simon Glass <sjg at chromium.org> who is sending
this series originally created by Thierry)

This series adds PCIe support for Tegra20, Tegra30 and Tegra124. The size is
mostly due to the large number of infrastructure that's added (Tegra-
specific drivers required by the PCIe driver). In this version I've included
all patches that were previously split into three separate series. Spreading
them over multiple series is probably not worth it since there might be some
dependencies between them and only the end result gives a completely working
setup.

Some patches have already been applied to this series.

Patch 1 implements a driver for the AS3722 PMIC used on the Venice2 and
Jetson TK1 boards.

Patches 2-7 are preparatory work for the Tegra PCIe controller. They add
missing clock driver functionality as well as drivers for the Tegra powergat
and XUSB pad controller blocks.

Patch 8 adds the PCIe controller driver for Tegra20, Tegra30 and Tegra124.

Device tree nodes and configurations options to enable PCIe on the TrimSlice
(Tegra20), Beaver, Cardhu (Tegra30) and Jetson TK1 (Tegra124) boards are
added in patches 9-17.

Patch 18 implements non-cached memory support that will be used in the
last batch of patches to implement more reliable packet transfers in the
r8169 driver. Patch 19 enables non-cached memory support on Tegra.

(Note from Simon: These patches may have already been applied in the ARM
tree, but I can't see them there).

Finally, patches 20-23 implement non-cached memory support and various fixes
in the r8169 driver and add support for the revision of the NIC found on the
Jetson TK1.

The above boards all have an ethernet NIC connected to PCIe, which is what
I tested with.

Note from Simon: I have:

- rebased this on top of the I2C driver model series
- dropped the I2C framework patches
- adjust the PMIC driver and code that calls it to use driver mode
- tested the I2C changes on Jetson-TK1

Changes in v4:
- Use const unsigned for bus and address
- Insert missing word 'to' in a comment
- Fix typo in commit message

Changes in v3:
- Use driver model for the PMIC
- Use driver model to access the PMIC
- Use driver model to access the PMIC
- Avoid build error with noncached_init() when the dcache is disabled
- Remove cache-line size warning if dcache is disabled
