c862b91d93 mtd: sf: Drop plat from sf_probe
dm_spi_slave_platdata used in sf_probe for printing
plat->cs value and there is no relevant usage apart
from this.

We have enough debug messages available in SPI and SF
areas so drop this plat get and associated bug statement.

46e4cdff1e mtd: spi: Call sst_write in _write ops
Currently spi-nor code is assigning _write ops for SST
and other flashes separately. 

Just call the sst_write from generic write ops and return
if SST flash found, this way it avoids the confusion of
multiple write ops assignment during the scan and makes
it more feasible for code readability.

No functionality changes.

f12f96cfaf sf: Drop spl_flash_get_sw_write_prot
The get_sw_write_prot API is used to get the write-protected
bits of flash by reading the status register and other wards
it's API for reading register bits.

1) This kind of requirement can be achieved using existing
   flash operations and flash locking API calls instead of
   making a separate flash API.
2) Technically there is no real hardware user for this API to
   use in the source tree.
3) Having a flash operations API for simple register read bits
   also make difficult to extend the flash operations.
4) Instead of touching generic code, it is possible to have
   this functionality inside spinor operations in the form of
   flash hooks or fixups for associated flash chips.

Considering all these points, this patch drops the get_sw_write_prot
and associated code bases.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

832ce20278 mtd: spi: Clean up usage of CONFIG_SPI_FLASH_MTD
Most boards currently use SPI_FLASH_MTD only in U-Boot proper, not in
SPL. They often rely on hacks in the board header files to include
this option conditionally. To be able to fix this, we previously
introduced a separate option SPL_SPI_FLASH_MTD.

Therefore we can now adjust the Makefile and change the code in
sf_probe.c and sf_internal.h to use CONFIG_IS_ENABLED(SPI_FLASH_MTD).

We also need to move all occurences of CONFIG_SPI_FLASH_MTD from the
header files to the according defconfigs. The affected boards are
socfpga, aristainetos, cm_fx6, display5, ventana, rcar-gen2, dh_imx6
and da850evm.

We do this all in one patch to guarantee bisectibility.

This change was tested with buildman to make sure it does not
introduce any regressions by comparing the resulting binary sizes.

989fd97fe5 mtd: spi: Kconfig: Update CONFIG_SPI_FLASH
1) CONFIG_SPI_FLASH is not just a legacy code, but it has common
   core code which handle both dm and non-dm spi flash code. So
   fix the info text to make it clear globally.

2) Since it's flash core it shouldn't depends on legacy SPI,
   so remove the 'depends on SPI'

27084c03d3 spl: Allow tiny printf() to be controlled in SPL and TPL
At present there is only one control for this and it is used for both SPL
and TPL. But SPL might have a lot more space than TPL so the extra cost of
a full printf() might be acceptable.

Split the option into two, providing separate SPL and TPL controls. The
TPL setting defaults to the same as SPL.

43084a56b0 mtd: spi_dataflash: Use spi read then write
Now, we have spi_write_then_read routine that would handle
spi_xfer handling based on the tx_buf and rx_buf parameters.

So, replace individual flash read/write/cmd transfer call
with spi_write_then_read.

mt25qu512a is rebranded after its spinoff from STM, so it is
different only in term of extended jedec ID, initial JEDEC id
is same as that of n25q512a.In order to avoid any confussion
with respect to name new entry is added.

This flash is tested for Single I/O mode on LS1046FRWY although
it also support QUAD I/O.

60e2bf4678 mtd: spi-nor: fix page program issue when using spi-mem driver
Some SPI controllers can't write nor->page_size bytes in a single step
because their TX FIFO is too small, but when that happens we should
make sure a WRITE_EN command before each write access and READ_SR command
after each write access is issued.

We should allow nor->write() to return a size that is smaller than the
requested write size to gracefully handle this case.

Also, the spi_nor_write_data() should return the actual number of bytes
that were written during the spi_mem_exec_op() operation.

This patch is a combination of two commits backported from kernel:

  commit 630d6bd8a3b4 ("mtd: spi-nor: Support controllers with limit ...")
  commit 3baa8ec88c2f ("mtd: devices: m25p80: Make sure WRITE_EN is ...")

b0cc1b846f dm: spi: Read default speed and mode values from DT
This patch update the behavior introduced by
commit 96907c0fe5 ("dm: spi: Read default speed and mode values from DT")

In case of DT boot, don't read default speed and mode for SPI from
CONFIG_* but instead read from DT node. This will make sure that boards
with multiple SPI/QSPI controllers can be probed at different
bus frequencies and SPI modes.

Remove also use in boards of the value speed=0 (no more supported)
for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0.

DT values will be always used when available (full DM support of
SPI slave with available DT node) even if speed and mode are requested;
for example in splash screen support (in splash_sf_read_raw)
or in SPL boot (in spl_spi_load_image).
The caller of spi_get_bus_and_cs() no more need to force speed=0.

But the current behavior don't change if the SPI slave is not
present (device with generic driver is created automatically)
or if platdata is used (CONFIG_OF_PLATDATA).
