8581d9927d Correct SPL uses of ZYNQMP_FIRMWARE
This converts 2 usages of this option to the non-SPL form, since there is
no SPL_ZYNQMP_FIRMWARE defined in Kconfig

ce8adf1a41 spi: cadence-qspi: Fix compilation error in mini u-boot flash reset
When cadence_qspi_versal_flash_reset() function is called in mini
u-boot where there is no firmware support, it is missing defines for
macro's BOOT_MODE_POR_0 & BOOT_MODE_POR_1. Remove them and replace with
already define macro's which have same values as these.

1e681448a3 spi: cadence_qspi: Add support for Versal NET platform
Trivial changes to support cadence ospi driver for Versal NET platform.
Also avoid ospi flash reset for now.

f7d4cab1b3 spi: cadence-qspi: Use priv instead of plat across the driver
As per driver model we should enumerate plat structure only in
of_to_plat() and should be used only in probe(). Copy required
plat structure info into priv structure in probe() and use priv
structure across the driver. So replace plat with priv structure across
the driver.

68852f3241 spi: cadence-qspi: Correct flash reset function name
In cadence_spi_probe, cadence_qspi_versal_flash_reset() is called to reset
the flash device. Looks like there is a mistake in previous series of
patches where it is defined as cadence_spi_versal_flash_reset() but
called as cadence_qspi_versal_flash_reset. Since there is a weak function
defined with the same name this issue was not caught.

Fix the issue by renaming cadence_spi_versal_flash_reset as
cadence_qspi_versal_flash_reset().

248fe9f302 spi: cadence_qspi: Enable apb linear mode for apb read & write operations
On versal platform, enable apb linear mode for apb read and write
execute operations amd disable it when using dma reads. This is done by
xilinx_pm_request() secure calls when CONFIG_ZYNQMP_FIRMWARE is enabled,
else we use direct raw reads and writes in case of mini U-Boot.

bf8dae5fcf spi: cadence-qspi: reset qspi flash for versal platform
When flash operated at non default mode like DDR, flash need to be reset
to operate in SDR mode to read flash ids by spi-nor framework. Reset the
flash to the default state before using the flash. This reset is handled
by a gpio driver, in case of mini U-Boot as gpio driver is disabled, we
do raw read and write access by the registers.
Versal platform utilizes spi calibration for read delay programming, so
incase by default read delay property is set in DT. We make sure not to
use read delay from DT by overwriting read_delay with -1.

cf553bf20e arm64: versal: Add versal specific cadence ospi driver
Add support for cadence ospi driver for Versal platform. This driver
provides support for DMA read operation which utilizes cadence qspi
driver.
If "cdns,is-dma" DT property is specified use dma for read operation
from cadence_qspi driver. As cadence_qspi_apb_dma_read() is defined in
cadence_ospi_versal driver add a weak function defination in
cadence_qspi driver.
