I use moveconfig script and then manual check on generated u-boot.cfg
to solve the remaining issue.

MTD: mxs_nand_spl: Redo the way nand_init initializes

Currently the spl system calls nand_init which does nothing.
It isn't until an attempt to load from NAND that it gets initialized.
Subsequent attempts to load just skip the initialization because
NAND is already initialized.

This moves the contents of mxs_nand_init to nand_init. In the event
of an error, it clears the number of nand chips found. Any
attempts to use nand will check if there are nand chips available
instead of actually doing the initialization at that time. If there
are none, it will return an error to the higher level calls.

MTD: nand: mxs_nand: Allow driver to auto setup ECC in SPL

The initialization of the NAND in SPL hard-coded ecc.bytes,

but it not appropriate for others. With the pending patch
"mxs_nand: Fix BCH read timeout error on boards requiring ECC"
the driver can auto configure the ECC when these entries are
blank. This patch has been tested in NAND flash with oob 64
and oob 128.

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.

Many SPI controllers have special MMIO interfaces which provide

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.

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Current U-Boot SPI NOR support (sf layer) is quite outdated as it does not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.
