The nor->ready() and spansion_sr_ready() introduced earlier in this
series are used for multi-die package parts.
The nor->quad_enable() sets the volatile QE bit on each die.
The nor->erase() is hooked if the device is not configured to uniform
sectors, assuming it has 32 x 4KB sectors overlaid on bottom address.
Other configurations, top and split, are not supported at this point.
Will submit additional patches to support it as needed.

Some of Spansion/Cypress chips have overlaid 4KB sectors at top and/or

non-overlaid portion of normal sector, and remaining normal sectors, by
selecting correct erase command and size based on the address to erase

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

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

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.

JESD216 rev D makes BFPT 20 DWORDs. Update the BFPT size define to
reflect that.
The check for rev A or later compared the BFPT header length with the
maximum BFPT length, BFPT_DWORD_MAX. Since BFPT_DWORD_MAX was 16, and so
was the BFPT length for both rev A and B, this check worked fine. But
now, since BFPT_DWORD_MAX is 20, it means this check will also stop BFPT
parsing for rev A or B, since their length is 16.
So, instead check for BFPT_DWORD_MAX_JESD216 to stop BFPT parsing for
the first JESD216 version, and check for BFPT_DWORD_MAX_JESD216B for the
next two versions.

The spi-mem layer provides a spi_mem_supports_op() function to check
whether a specific operation is supported by the controller or not.
This is much more accurate than the hwcaps selection logic based on
SPI_{RX,TX}_ flags.
Rework the hwcaps selection logic to use spi_mem_supports_op().
To make sure the build doesn't break for boards not using CONFIG_DM_SPI,
add a simple SPI_{RX,TX}_ based hwcaps selection logic in spi-mem-nodm
similar to spi_mem_default_supports_op(). This change is only
compile-tested.
To avoid SPL size problems on the x530 board, the old hwcaps selection
is still kept around. Leaving the code in-place was getting difficult to
read and understand, so the code is restructured to have it all in one
isolated function. As a result of this, the parameter hwcaps to
spi_nor_setup() is no longer needed. Remove it.

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.
Since spi-nor-tiny shouldn't have those fixup hooks populated, add a
separate function that lets flashes populate their fixup hooks.

This feature was dropped from U-Boot some time ago:
f12f96cfaf5 (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.
