On devices with non-uniform sector sizes like Spansion S25 or S28 family
of flashes the sector under erase does not necessarily have to be
mtd->erasesize bytes long. For example, on S28 flashes the first 128 KiB
region is composed of 32 4 KiB sectors, then a 128 KiB sector, and then
256 KiB sectors till the end.
Let the flash-specific erase functions erase less than the requested
length in case of the 4 or 128 KiB sectors and report the number of
bytes erased back to the calling function.

When the flash is handed to us in a stateful mode like 8D-8D-8D, it is
difficult to detect the mode the flash is in. One option is to read SFDP
in all modes and see which one gives the correct "SFDP" signature, but
not all flashes support SFDP in 8D-8D-8D mode.
Further, even if you detect the mode of the flash via SFDP, you still
have the problem of actually reading the ID. The Read ID command is not
standardized across flash vendors. Flashes can have different dummy
cycles needed for reading the ID. Some flashes even expect a 4-byte
dummy address with the Read ID command. All this information cannot be
obtained from the SFDP table.
So, perform a Software Reset sequence before reading the ID and
initializing the flash. A Soft Reset will bring back the flash in its
default protocol mode assuming no non-volatile configuration was set.
This will let us detect the flash even if ROM hands it to us in Octal
DTR mode.
To accommodate cases where there is more than one flash on a board, and
only one of them needs a soft reset, failure to reset is not made fatal,
and we still try to read ID if possible.

On probe, the SPI NOR core will put a flash in 8D-8D-8D mode if it
supports it. But Linux as of now expects to get the flash in 1S-1S-1S
mode. Handing the flash to Linux in Octal DTR mode means the kernel will
fail to detect the flash.
So, we need to reset to Power-on-Reset (POR) state before handing off
the flash. A Software Reset command can be used to do this.
One limitation of the soft reset is that it will restore state from
non-volatile registers in some flashes. This means that if the flash was
set to 8D mode in a non-volatile configuration, a soft reset won't help.
This commit assumes that we don't set any non-volatile bits anywhere,
and the flash doesn't have any non-volatile Octal DTR mode
configuration.
Since spi-nor-tiny doesn't (and likely shouldn't) have
spi_nor_soft_reset(), add a dummy spi_nor_remove() for it that does
nothing.

now, since BFPT_DWORD_MAX is 20, it means this check will also stop BFPT

Sometimes the information in a flash's SFDP tables is wrong. Sometimes
some information just can't be expressed in the SFDP table. So,
introduce the fixup hooks to allow tailoring settings for a specific
flash.
Three hooks are added: default_init, post_sfdp, and post_bfpt. These
allow tweaking the flash settings at different point in the probe
sequence. Since the hooks reside in nor->info, set that value just
before the call to spi_nor_init_params().
The hooks and at what points they are executed mimics Linux's spi-nor
framework. One major difference is that Linux puts the struct
spi_nor_fixups in nor->info. This is not possible in U-Boot because the
spi-nor-ids list is shared between spi-nor-core.c and spi-nor-tiny.c.

This feature was dropped from U-Boot some time ago:
f12f96cfaf (sf: Drop spl_flash_get_sw_write_prot")
However, we do need a way to see if a flash device is write-protected,
since if it is, it may not be possible to write to do (i.e. failing to
write is expected).
I am not sure of the correct layer to implement this, so this patch is a
stab at it. If spi-flash makes sense then I will add to the 'sf' also.
Re the points mentioned in the removal commit:
1) This kind of requirement can be achieved using existing
flash operations and flash locking API calls instead of
making a separate flash API.
Which uclass is this?
2) Technically there is no real hardware user for this API to
use in the source tree.
I do want coral (at least) to support this.
3) Having a flash operations API for simple register read bits
also make difficult to extend the flash operations.
This new patch only mentions write-protect being on or off, rather than
the actual mechanism.
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.
That sounds to me like what drivers are for. But we still need some sort
of API for it to be accessible.

This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.
Before this change it was necessary to use:
/* SPI Flash Configs */
#if defined(CONFIG_SPL_BUILD)
#undef CONFIG_DM_SPI
#undef CONFIG_DM_SPI_FLASH
#undef CONFIG_SPI_FLASH_MTD
#endif
in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.
The goal of this patch:
Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.
Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).
In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):
- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
environment with no fitImage and OF_LIBFDT support).
Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.
This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

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.

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.

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.
