87a6d86571 mtd: spi-nor: Add support for Infineon s25fs256t
Infineon S25FS256T is 256Mbit Quad SPI NOR flash. The key features and
differences comparing to other Spansion/Cypress flash familes are:
  - 4-byte address mode by factory default
  - Quad mode is enabled by factory default
  - Supports mixture of 128KB and 64KB sectors by OTP configuration
    (this patch supports uniform 128KB only)

53f4ef0a4b spi: cadence_qspi: use STIG mode for small reads
Fix the issue where some flash chips like cypress S25HS256T return the
value of the same register over and over in DAC mode.

For example in the TI K3-AM62x Processors refer [0] Technical Reference
Manual there is a layer of digital logic in front of the QSPI/OSPI
Drive when used in DAC mode. This is part of the Flash Subsystem (FSS)
which provides access to external Flash devices.

The FSS0_0_SYSCONFIG Register (Offset = 4h) has a BIT Field for
OSPI_32B_DISABLE_MODE which has a Reset value = 0. This means, OSPI 32bit
mode enabled by default.

Thus, by default controller operates in 32 bit mode causing it to always
align all data to 4 bytes from a 4byte aligned address. In some flash
chips like cypress for example if we try to read some regs in DAC mode
then it keeps sending the value of the first register that was requested
and inorder to read the next reg, we have to stop and re-initiate a new
transaction.

This causes wrong register values to be read than what is desired when
registers are read in DAC mode. Hence if the data.nbytes is very less
then prefer STIG mode for such small reads.

2330af2722 spi: cadence_qspi: setup ADDR Bits in cmd reads
Setup the Addr bit field while issuing register reads in STIG mode. This
is needed for example flashes like cypress define in their transaction
table that to read any register there is 1 cmd byte and a few more address
bytes trailing the cmd byte. Absence of addr bytes will obviously fail
to read correct data from flash register that maybe requested by flash
driver because the controller doesn't even specify which address of the
flash register the read is being requested from.

54a08c4139 ddr: marvell: a38x: Add support for DDR4 from Marvell mv-ddr-marvell repository
This syncs drivers/ddr/marvell/a38x/ with the master branch of repository
https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git

up to the commit "mv_ddr: a3700: Use the right size for memset to not overflow"
d5acc10c287e40cc2feeb28710b92e45c93c702c

This patch was created by following steps:

	1. Replace all a38x files in U-Boot tree by files from upstream github
	Marvell mv-ddr-marvell repository.

	2. Run following command to omit portions not relevant for a38x, ddr3, and ddr4:

	files=drivers/ddr/marvell/a38x/*
	unifdef -m -UMV_DDR -UMV_DDR_ATF -UCONFIG_APN806 \
		-UCONFIG_MC_STATIC -UCONFIG_MC_STATIC_PRINT -UCONFIG_PHY_STATIC \
		-UCONFIG_PHY_STATIC_PRINT -UCONFIG_CUSTOMER_BOARD_SUPPORT \
		-UCONFIG_A3700 -UA3900 -UA80X0 -UA70X0 -DCONFIG_ARMADA_38X -UCONFIG_ARMADA_39X \
		-UCONFIG_64BIT $files

	3. Manually change license to SPDX-License-Identifier
	(upstream license in  upstream github repository contains long license
	texts and U-Boot is using just SPDX-License-Identifier.

After applying this patch, a38x, ddr3, and ddr4 code in upstream Marvell github
repository and in U-Boot would be fully identical. So in future applying
above steps could be used to sync code again.

The only change in this patch are:
	1. Some fixes with include files.
	2. Some function return and basic type defines changes in
	mv_ddr_plat.c (to correct Marvell bug).
	3. Remove of dead code in newly copied files (as a result of the
	filter script stripping out everything other than a38x, dd3, and ddr4).

17e8e58fe6 Merge https://source.denx.de/u-boot/custodians/u-boot-sunxi
This contains some fixes, and the first bunch of some clean up patches
to get rid of legacy GPIO and PMIC code.
Highlight is the DM AXP PMIC driver, which is required to convert some
drivers over to use DM regulators, and also is required to get rid
of some less optimal PMIC setup code in Trusted Firmware. This isn't
enabled by any defconfig yet, but can be enabled manually and works. For
the full glory some patches are still missing, and this requires more
testing, which would be simpler if the core code is upstream.

4e1ab2065e Merge branch '2023-01-24-bootstd-allow-migration-from-distro_bootcmd-script'
To quote the author:
So far, standard boot does not replicate all the of the functionality
of the distro_bootcmd scripts. In particular it lacks some bootdevs and
some of the bootmeths are incomplete.

Also there is currently no internal mechanism to enumerate buses in order
to discover bootdevs, e.g. with USB.

This series addresses these shortcomings:

- Adds the concept of a 'bootdev hunter' to enumerate buses, etc. in an
  effort to find bootdevs of a certain priority
- Adds bootdevs for SCSI, IDE, NVMe, virtio, SPI flash
- Handles PXE and DHCP properly
- Supports reading the device tree with EFI and reading scripts from the
  network

It also tidies up label processing, so it is possible to use:

   bootflow scan mmc2

to scan just one MMC device (with BOOTSTD_FULL).

As before this implementation still relies on CONFIG_CMDLINE being
enabled, mostly for the network stack. Further work would be required to
disentangle that.

Quite a few tests are added but there are some gaps:

- SPI flash bootdev
- EFI FDT loading

Note that SATA works via SCSI (CONFIG_SCSI_AHCI) and does not use
driver model. Only pogo_v4 seems to be affected. Probably all thats is
needed is to call bootdev_setup_sibling_blk() in the Marvell SATA driver.

Also, while it would be possible to init MMC in a bootdev hunter, there is
no point since U-Boot always inits MMC on startup, if present.

With this series it should be possible to migrate boards to standard boot
by removing the inclusion of config_distro_bootcmd.h and instead adding
a suitable value for boot_targets to the environment, e.g.:

   boot_targets=mmc1 mmc0 nvme scsi usb pxe dhcp spi

Thus it is possible to boot automatically without scripts and boards can
use a text-based environment instead of the config.h files.

To demonstrate this, rockpro64-rk3399 is migrated to standard boot in this
series. Full migration could probably be automated using a script, similar
in concept to moveconfig:

   - obtain the board environment via 'make u-boot-initial-env'
   - get the value of "boot_targets"
   - drop config_distro_bootcmd.h from the config.h file
   - rebuild again to get the environment without distro scripts
   - write the environment (adding boot_targets) to board.env
   - remove CONFIG_EXTRA_ENV_SETTINGS from the config.h file

47aedc29dc bootstd: Switch bootdev scanning to use labels
At present we set up the bootdev order at the start, then scan the
bootdevs one by one.

However this approach cannot be used with hunters, since the bootdevs may
not exist until the hunter is used. Nor can we just run all the hunters at
the start, since that violate's U-Boot's 'lazy init' requirement. It also
increases boot time.

So we need to adjust the algorithm to scan by labels instead. As a first
step, drop the dev_order[] array in favour of a list of labels. Update the
name of bootdev_setup_iter_order() to better reflect what it does.

Update some related comments and log messages. Also disable a few tests
until a later commit where we can use them.

2b3ebf2013 ata: Don't try to use non-existent ports
The controller indicates the number of ports but also has a port map
which specifies which ports are actually valid. Make use of this to
avoid trying to send commands to an invalid port.

This avoids a crash on some controllers.

00fc8cade8 virtio: Add a block device
The test code for virtio is fairly simplistic and does not actually create
a block device. Add a way to specify the device type in the device tree.
Add a block device so that we can do more testing.

811c81e889 virtio: Fix returning -ENODEV
This has a special meaning in driver model. There is clearly a device, so
it does not make sense to return this error code. Fix it.
