u-boot-rockchip changes for 2019.04-rc1:
  * support for Chromebook Bob
  * full pinctrl driver using DTS properties
  * documentation improvements
  * I2S support for some Rockchip SoCs

- MIPS: mscc: jr2: small fixes
- MIPS: mscc: luton: add ethernet and switch driver
- MIPS: mt76xx: fix timer frequency

- Various TI platforms have been updated and DTS files re-synced and
  options disabled if not used or migrated to the DM versions
- Improvements to the dumpimage tool
- Rename SPL FAT/EXT filesystem support symbols for consistency and then
  allow them to be used to save more space in SPL.
- More lmb fixes
- Partial migration of CONFIG_BUILD_TARGET

Now that BUILD_TARGET is in Kconfig we can define a default for boards
using the Kirkwood SoC.

There are 3 supported modes of operation:

The dump image utility has very confusing syntax. If called to list image
contents ("-l") it takes the image name as a positional argument. If the
utility is called to extract something from the image, the image must be
provided via the optional argument "-i" as well as the positional argument
but the value passed in the positional argument will be completely
ignored.

Simplify dumpimage by always providing the image as the first positional
argument. Assume we want to dump something from the image if we do not
provide the "-l" option for now.

Bob is a 10-inch chromebook produced by Asus. It has two USB 3.0 type-C
ports, 4GB of SDRAM, WiFi and a 1280x800 display. It uses its USB ports
for both power and external display. It includes a Chrome OS EC
(Cortex-M3) to provide access to the keyboard and battery functions.

Support so far includes only:
- UART
- SDRAM
- MMC, SD card
- Cros EC (but not keyboard)

Not included:
- Keyboard
- Display
- Sound
- USB
- TPM

Bob is quite similar to Kevin, the Samsung Chromebook Plus, but support
for this is not provided in this series.

In space-constrained environments or before driver model is available, it
is sometimes necessary to set GPIO values. Add an SPL API for this, to
allow early board code to change GPIOs. The caller must provide the
register address, so that the drivers can be fairly generic.

This API can be implemented by GPIO drivers, behind a suitable guard,
like #ifdef CONFIG_SPL_BUILD.
