[U-Boot] [PATCH v3 0/16] tegra: Add fdt definitions and USB driver

[Simon Glass]

This series brings in the kernel fdt file and provides a working
USB driver for Tegra2 Seaboard.

(I have done this in one series since otherwise most of the fdt additions
will just look like dead code.)

The driver requires CONFIG_OF_CONTROL and a device tree to operate.

Some enhancements to fdtdec are required to make this easier, and these
are included in the series also. I have had to bring in basic GPIO
support due to the request to put the USB VBUS into the fdt.

Since the kernel recently got a very minimal USB binding, I have started
with that and extended it where appropriate.

Tegra likes to have cache-aligned buffers. I have dropped the patch which
implements this since we will solve this problem by making callers align
their buffers (as we did with MMC).

Changes in v2:
- Use "okay" instead of "ok" for fdt node status
- Remove 0x from fdt aliases
- Rename params to timing
- Store entire fdt config in port list, not just register pointer
- Remove non-fdt operation of USB, since it is not needed
- Decode USB VBUS GPIO from the fdt
- Decode phy type differently (to match new kernel fdt)
- Rename tegra20-usb to tegra20-ehcui (to match new kernel fdt)
- Improve debug() printouts in case of failure to init USB
- Add setting of pinmux for USB VBUS GPIO
- Remove unneeded CONFIG_TEGRA_USBx defines

Changes in v3:
- Remove "okay" from nodes since this is the default anyway
- Fix device tree indenting with tabs instead of spaces
- Disable USB2 which is not used on Seaboard
- Remove usbparams properties from fdt and moved them to C code
- Drop Tegra USB alignment patch as we will deal with this another way
