Remove xlnx-versal-power.h dt binding header because they should be moved
directly to folder where DTs are. In the Linux kernel this shift already
started by moving xlnx-zynqmp-clk.h to arch/arm64/boot/dts/xilinx/ folder.
U-Boot is using only one PD_DEV_OSPI constact which is moved to
zynqmp_firmware.h header. But handling around it should be fixed anyway
because no driver should be calling xilinx_pm_request() directly.

This patch ports the Cadence xSPI controller driver from
the Linux kernel. The controller supports three operating modes:
1. ACMD (Auto Command) mode
- Includes PIO and CDMA submodes.
- CDMA mode uses linked descriptors for high-performance,
low-overhead operation.
- PIO mode is suitable for simple, single-command transactions.
2. STIG (Software Triggered Instruction Generator) mode
- Issues low-level 128-bit instructions to memory.
- Uses the Slave DMA interface for data transfers.
3. Direct mode
- Enables direct data access through the slave interface
without commands.
Currently, only the STIG work mode is enabled. Additional modes will be
supported in future updates.
At the same time, also enabling the kconfig option for xSPI driver.
This driver has been ported and functionally verified on the Intel Simics
platform. It is intended for evaluation and experimental use at this stage.

We found that some serial console may pull TX line to GROUND during board
boot time. Airoha uses TX line as one of it's BOOT pins. This will lead
to booting in RESERVED boot mode.
It was found that some flashes operates incorrectly in RESERVED mode.
Micron and Skyhigh flashes are definitely affected by the issue,
Winbond flashes are NOT affected.
Details:
--------
DMA reading of odd pages on affected flashes operates incorrectly. Page
reading offset (start of the page) on hardware level is replaced by 0x10.
Thus results in incorrect data reading. Usage of UBI make things even
worse. Any attempt to access UBI leads to ubi damaging. As result OS loading
becomes impossible.
Non-DMA reading is OK.
This patch detects booting in reserved mode, turn off DMA and print big
fat warning.

The spinand driver do 3 type of dirmap requests:
* read/write whole flash page without oob
(offs = 0, len = page_size)
* read/write whole flash page including oob
(offs = 0, len = page_size + oob_size)
* read/write oob area only
(offs = page_size, len = oob_size)
The trick is:
* read/write a single "sector"
* set a custom sector size equal to offs + len. It's a bit safer to
round up "sector size" value 64.
* set the transfer length equal to custom sector size
And it works!
Thus we can find all data directly from dirmap request, so flash specific
parameters is not needed anymore. Also
* airoha_snand_nfi_config(),
* airoha_snand_nfi_setup()
functions becomes unnecessary.

This driver can accelerate single page operations only, thus

If dirmap is disabled or not supported in the spi driver, the dirmap requests
will be executed via exec_op() handler. Thus, if the hardware supports
dual/quad spi modes, then corresponding requests will be sent to exec_op()
handler. Current driver does not support such requests, so error is arrised.
As result the flash can't be read/write.
This patch adds support of dual and quad wires spi modes to exec_op() handler.

Coverity finds a potential integer overflow in the following code:
ncycles += ((op->data.nbytes * 8) / op->data.buswidth) / (op->data.dtr ? 2 : 1);
A quick analysis shows that the only caller of the suspicious code is the
spinand_select_op_variant() function from the drivers/mtd/nand/spi/core.c
file.
According to the code the value of op->data.nbytes is equal to
nanddev_per_page_oobsize(nand) + nanddev_page_size(nand)
Therefore it's maximum value a bit larger than 4Kb (I never seen flashes
with page size large than 4Kb). So op->data.nbytes always fits within
13 bits. As result an overflow will never happen.
Anyway it's better fix an issue to eliminate the error message.

Currently the best variant picked in the first one in the list provided
in the manufacturer driver. This worked well while all operations where
performed at the same speed, but with the introduction of DTR transfers
this no longer works correctly.
Let's continue iterating over all the alternatives, even if we find a
match, keeping a reference over the theoretically fastest
operation. Only at the end we can tell which variant is the best.
This logic happening only once at boot.

and cause data corruption in the returned data, with no failure report.
Even a single A35 core accessing both these regions can trigger the issue
because an A35 core can have more than one parallel read operation in

In atmel_qspi_transfer(), the status register is polled with:
imr = QSPI_SR_INSTRE | QSPI_SR_CSR;
return readl_poll_timeout(aq->regs + QSPI_SR, sr,
(sr & imr) == imr,
ATMEL_QSPI_TIMEOUT);
However, this is racy: QSPI_SR_INSTRE can be set before QSPI_SR_CSR,
and will then be cleared by the read. If that happens, the condition
"(sr & imr) == imr" can never be true, and the function times out.
This race condition is avoided in at91bootstrap by accumulating the
status bits across reads until both bits have been observed:
/* Poll INSTruction End and Chip Select Rise flags. */
imr = (QSPI_SR_INSTRE | QSPI_SR_CSR);
sr = 0;
do {
udelay(1);
sr |= qspi_readl(qspi, QSPI_SR) & imr;
} while ((--timeout) && (sr != imr));
