Many SPI controllers have special MMIO interfaces which provide
accelerated read/write access but require knowledge of flash parameters
to make use of it. Recent spi-mem layer provides a way to support such
controllers.
Therefore, add spi-mem support to spi-nor-core as a way to support SPI
controllers with MMIO interface. SPI MEM layer takes care of translating
spi_mem_ops to spi_xfer()s in case of legacy SPI controllers.

Current U-Boot SPI NOR support (sf layer) is quite outdated as it does not
support 4 byte addressing opcodes, SFDP table parsing and different types of
quad mode enable sequences. Many newer flashes no longer support BANK

above features. Start with basic sync up that brings in basic framework

  * 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

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.
