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 ...")

5f626e7849 mtd: nand: raw: Fix CONFIG_SYS_NAND_DRIVER_ECC_LAYOUT behavior
The purpose of "mtd: nand: raw: allow to disable unneeded ECC layouts"
was to allow disabling the default ECC layouts if a driver is known to
provide its own ECC layout. However, this commit did the opposite and
disabled the default layout when it was _not_ selected.

It breaks all the NAND drivers not providing their own ECC layout this
patch fix this situation.

It was tested with the lpc32xx_nand_slc driver.

9db29b300f mtd: nand: provide several helpers to do common NAND operations
Linux commit 97d90da8a88 ("mtd: nand: provide several helpers
to do common NAND operations")

This is part of the process of removing direct calls to ->cmdfunc()
outside of the core in order to introduce a better interface to execute
NAND operations.

Here we provide several helpers and make use of them to remove all
direct calls to ->cmdfunc(). This way, we can easily modify those
helpers to make use of the new ->exec_op() interface when available.

7bb75023a7 mtd: rawnand: stm32_fmc2: add STM32 FMC2 NAND flash controller driver
The driver adds the support for the STMicroelectronics FMC2 NAND
Controller found on STM32MP SOCs.

This patch adds the polling mode, a basic mode that do not need
any DMA channels.

Only NAND_ECC_HW mode is actually supported.
The driver supports a maximum 8k page size.
The following ECC strength and step size are currently supported:
 - nand-ecc-strength = <8>, nand-ecc-step-size = <512> (BCH8)
 - nand-ecc-strength = <4>, nand-ecc-step-size = <512> (BCH4)
 - nand-ecc-strength = <1>, nand-ecc-step-size = <512> (Extended ECC
   based on Hamming)

This patch has been tested on Micron MT29F8G08ABACAH4.

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).

f909ddb3e1 mtd: spi: Replace ad-hoc default implementation with spi_mem_op
Replace the ad-hoc erase operation implementation with a simple spi_mem_op
implementation of the same functionality. This is a minor optimization and
removal of the ad-hoc code.

This however also changes the behavior of the execution of the erase
opcode from two separate transfer requests to the SPI NOR driver to
one transfer request to the SPI NOR driver. The former was how U-Boot
behaved before the SPI NOR framework was imported and the later was
introduced by the SPI NOR framework. The former is more optimal, so
keep that.

3f3aef4b9d mtd: fix Coverity integer handling issue
A Coverity robot reported an integer handling issue
(OVERFLOW_BEFORE_WIDEN) in the potentially overflowing expression:

    (mtd_div_by_ws(mtd->size, mtd) - mtd_div_by_ws(offs, mtd)) *
    mtd_oobavail(mtd, ops)

While such overflow will certainly never happen due to the numbers
handled, it is cleaner to fix this operation anyway.

The problem is that all the maths include 32-bit quantities, while the
result is stored in an explicit 64-bit value.

As maxooblen will just be compared with a size_t, let's change the
type of the variable to a size_t. This will not fix anything but will
clarify a bit the situation. Then, do an explicit cast to fix Coverity
warning.

- OOB layout changed to only reserve 1 byte for BBT
- Use ECC caps 8bits/512bytes instead of 8bits/2048bytes

d46d27d3b6 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.

a38c3af868 mtd: nand: raw: allow to disable unneeded ECC layouts
Each ECC layout consumes about 2984 bytes in the .data section. Allow
to disable the default ECC layouts if a driver is known to provide its
own ECC layout.

254409dbe8 nand: vybrid: Use calloc() instead of malloc() to allocate struct nfc
Without this change it is possible that Vybrid's NFC driver malloc() call
will obtain some memory used (and correctly free'd) by some previous
driver (in this case pinctrl for Vybrid).

As a result some fields of struct nfc - in out case mtd->_get_device - are
"pre initialized" with some random values.

On the latter stage of booting, when e.g. somebody calls 'mtdparts default'
the "data abort" is observed when __get_mtd_device() function is called.

The mtd->_get_device pointer is not NULL and wrong value is referenced.

8ccfbfb3e1 mtd: rawnand: denali: optimize timing parameters for data interface
Based on Linux commit 1dfac31a5a63ac04a9b5fbc3f5105a586560f191

This commit improves the ->setup_data_interface() hook.

The denali_setup_data_interface() needs the frequency of clk_x
and the ratio of clk_x / clk.

The latter is currently hardcoded in the driver, like this:

  #define DENALI_CLK_X_MULT       6

The IP datasheet requires that clk_x / clk be 4, 5, or 6.  I just
chose 6 because it is the most defensive value, but it is not optimal.
By getting the clock rate of both "clk" and "clk_x", the driver can
compute the timing values more precisely.

To not break the existing platforms, the fallback value, 50 MHz is
provided.  It is true for all upstreamed platforms.

a13fe7afe9 mtd: rawnand: denali_dt: add more clocks based on IP datasheet
Based on Linux commit 6f1fe97bec349a1fd6c5a8c7c5998d759fe721d5

Currently, denali_dt.c requires a single anonymous clock, but
the Denali User's Guide requires three clocks for this IP:

 - clk: controller core clock

 - clk_x: bus interface clock

 - ecc_clk: clock at which ECC circuitry is run

This commit supports these named clocks to represent the real hardware.

For the backward compatibility, the driver still accepts a single clock
just as before.  The clk_x_rate is taken from the clock driver again if
the named clock "clk_x" is available.  This will happen only for future
DT, hence the existing DT files are not affected.

08898e8b22 mtd: sf: Make sf_mtd.c more robust
SPI flash based MTD devs can be registered/unregistered at any time
through the sf probe command or the spi_flash_free() function.

This commit does not try to fix the root cause as it would probably
require rewriting most of the code and have an mtd_info object
instance per spi_flash object (not to mention that the the spi-flash
layer is likely to be replaced by a spi-nor layer ported from Linux).

Instead, we try to be as safe as can be by checking the code returned
by del_mtd_device() and complain loudly when there's nothing we can
do about the deregistration failure. When that happens we also reset
sf_mtd_info.priv to NULL, and check for NULL pointer in the mtd hooks
so that -ENODEV is returned instead of hitting a NULL pointer
dereference exception when the MTD instance is later accessed by a user.
