Fix the issue where some flash chips like cypress S25HS256T return the

chips like cypress for example if we try to read some regs in DAC mode

This causes wrong register values to be read than what is desired when

3. Manually change license to SPDX-License-Identifier

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).
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.
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

bootstd: Support reading a script from network or SPI flash
At present this bootmeth only supports a block device and the sandbox
host filesystem. Add support for obtaining the script from a network
device. Also implement the set_bootflow() method so that it is easy
for other bootdevs (such as enabling SPI flash to support scripts).

sandbox: Allow SPI flash bootdevs to be disabled for tests
Most tests don't want these and they can create a lot of noise. Add a way
to disable them. Use that in tests, with a flag provided to enable them
for tests that need this feature.

bootstd: Move label parsing into its own function
This is complicated enough to merit its own function, particularly as we
are about to add to it. Create a new label_to_uclass() function to decode
a label.
Also update the code to ignore an empty label or one consisting of just a
number.

bootstd: Support reading the device tree with EFI
With EFI booting the device tree is required but is not actually specified
in any way. The normal method is to use a fdtfile environment variable to
get the filename, then look for that file on the media.

bootstd: Include the device tree in the bootflow
Some bootmeths provide a way to load a device tree as well as the base
OS image. Add a way to store this in the bootflow. Update the
'bootflow info' command to show this information.
Note that the device tree is not allocated, but instead is stored at
an address provided by an environment variable. This may need to be
adjusted at some point, but for now it works well and fits in with the
existing distro-boot scripts.

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.

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.
