75b2ec2a22 configs: Remove SF_DUAL_FLASH
SF_DUAL_FLASH claims to enable support for SF_DUAL_STACKED_FLASH and
SF_DUAL_PARALLEL_FLASH. But, in current U-Boot code, grepping for above
enums yield no user and therefore support seems to be incomplete. Remove
these configs so as to avoid confusion.

7287597870 spl: Kconfig: Enable SPI_FLASH_TINY by default for SPL
SPL only needs to be able to read from SPI Flash to load next stage and
does not really need write/erase etc. Therefore in order to reduce SPI
Flash code size in SPL, enable SPI_FLASH_TINY, that only supports
reading from SPI flash, as default.

Note: Since, SPI_FLASH_TINY does not support SPI_FLASH_BAR,
SPI_FLASH_TINY is not enabled for boards with SPI controllers that
cannot support 4 byte addressing.

778572d7cb mtd: spi: Add lightweight SPI flash stack for SPL
Add a tiny SPI flash stack that just supports reading data/images from
SPI flash. This is useful for boards that have SPL size constraints and
would need to use SPI flash framework just to read images/data from
flash. There is approximately 1.5 to 2KB savings with this.

Based on prior work of reducing spi flash id table by

492e65b29b mtd: spi: spi-nor-core: Add SPI MEM support
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.

7aeedac015 mtd: spi: Port SPI NOR framework from Linux
Current U-Boot SPI NOR support (sf layer) is quite outdated as it does not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
registers used by sf layer to a access >16MB of flash address space.
So, sync SPI NOR framework from Linux v4.19 that supports all the
above features. Start with basic sync up that brings in basic framework
subsequent commits will bring in more features.

At present this enum is only available to rk3288. Move it so that other
rockchip SoCs can access it. It is needed for the SPL GPIO driver for
rk3999 in a later patch.

Also adjust the enum name to lower case.

Add mention of a prerequisite needed to build the image. Also adjust the
English wording in a few places.

Ideally this should move to using binman to produce images, and avoid the
manual steps.

0a09f2f117 rockchip: Adjust rk3399 device tree to be closer to linux
This file has changed upstream, with some additions and changes. Move the
U-Boot version towards this.

Some USB changes seem to be incompatible with how the bindings work on
rockchip in U-Boot. Testing is needed to make sure that USB still works
correct, and adjust the code (not device tree) if not.
