d65e8da92e common: Implement A/B metadata
This patch determines the A/B-specific bootloader message structure
that is the basis for implementation of recovery and A/B update
functions. A/B metadata is stored in this structure and used to decide
which slot should we use to boot the device. Also some basic functions
for A/B metadata manipulation are implemented (like slot selection).

The patch was extracted from commits [1], [2] with some coding style
fixes.

79536013a3 usb: Rename SPL_USB_SUPPORT to SPL_USB_STORAGE
Since there is the SPL_USB_HOST_SUPPORT for enabling USB support in SPL,
makes more sense to rename the SPL_USB_SUPPORT as SPL_USB_STORAGE.
Everything that is not part of the usb storage support in SPL is now
build under SPL_USB_HOST_SUPPORT.

2dd468dbe1 dfu: Remove dependency on HUSH parser in SPL
CLI support with the HUSH parser is not currently SPL safe due to it's
use of realloc. That function is not defined for SPLs that use
SYS_MALLOC_SIMPLE. CLI support can be built in to SPL and some functions
do work, but use of some like run_command() will cause build to fail.
When no SPL code calls this function build works as the compiler removes
this unreachable code so the unresolved symbols are ignored.

If DFU support is enabled in SPL then MMU DFU support may get brought in
also, this code does make a call to run_command() causing build to fail
if the HUSH parser is not built-in. To break this odd and unneeded
dependency chain we use CONFIG_IS_ENABLED where appropriate to prevent
calls into HUSH code from SPL. This also removes our need to pull in the
rather unrelated source file when SPL_DFU is defined.

7d98dbcc3d usb: musb-new: Add support for DM_USB
Enable DM for USB peripheral in the musb-new driver.
Also make sure that the driver can be used in the SPL.
This implies that:
* the driver must work with and without the OF_CONTROL option. That
in turn, implies that the platform data can be passed in a struct
ti_musb_platdata or be read from the dtb
* usb.o is linked in the SPL if host support is enabled

Another change is that the driver does not fail to bind (and stop the boot
process) if one of the child driver does not bind. Reporting the error is
enough. This kind of error would appear if the port is configured in the
DTS but the driver is not activated in the config.

9f407d4ef0 Add core support for a bloblist to convey data from SPL
At present there is no standard way in U-Boot to pass information from SPL
to U-Boot proper. But sometimes SPL wants to convey information to U-Boot
that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM
then it might want to pass the size of SDRAM, or the location of each
bank, to U-Boot proper.

Add a new 'bloblist' feature which provides this. A bloblist is set up in
the first phase of U-Boot that runs (i.e. TPL or SPL). The location of
this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else.

Information placed in this region is preserved (with a checksum) through
TPL and SPL and ends up in U-Boot. At this point it is copied into SDRAM
so it can be used after relocation.

b0aa74a264 avb2.0: add proper dependencies
1. Since libavb library alone is highly portable, introduce dedicated
Kconfig symbol for AVB bootloader-dependent operations, so it's possible
to build libavb separately. AVB bootloader-dependent operations include:
  * Helpers to process strings in order to build OS bootargs.
  * Helpers to access MMC, similar to drivers/fastboot/fb_mmc.c.
  * Helpers to alloc/init/free avb ops.
2. Add CONFIG_FASTBOOT dependency, as fastboot buffer is
re-used in partition verification operations.

Implement AVB ops on top of existing mmc subsystem API. Currently there
is a full implementation of such operations, defined by [1]
AVB2.0 specification:

.read_from_partition() - reads N bytes from a partition identified by
a name.
.write_to_partition() - Writes N bytes to a partition identified by a name.
.validate_vbmeta_public_key() - checks if the given public ‘vbmeta’
partition is trusted.
.get_unique_guid_for_partition() - Gets the GUID for a partition identified
by a string name.

As [1] specification recommends to use tamper-evident storage for storing
rollback indexes and device state (LOCKED/UNLOCKED),
currently are only stubs instead of full implementation for these ops:
.read_rollback_index() - Gets the rollback index for a given index location
.write_rollback_index() - Sets the rollback index to a given location
.read_is_device_unlocked() - Gets where the device is unlocked

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

  # This option is not just y/n - it can have a numeric value
  ifdef CONFIG_BOOTDELAY
  obj-y += autoboot.o
  endif

It was a bit odd to enable/disable code with an integer type option,
but it was how this option worked before that commit, and several
boards actually unset it to opt out of the autoboot feature.

This commit adds a new bool option, CONFIG_AUTOBOOT, and makes
CONFIG_BOOTDELAY depend on it.

I chose "default y" for this option because most boards use the
autoboot.  I added "# CONFIG_AUTOBOOT is not set" for the boards that
had not set CONFIG_BOOTDELAY prior to the bad commit.

51c14cd128 verified-boot: Minimal support for booting U-Boot proper from SPL
This allows a board to configure verified boot within the SPL using
a FIT or FIT with external data. It also allows the SPL to perform
signature verification without needing relocation.

The board configuration will need to add the following feature defines:
CONFIG_SPL_CRYPTO_SUPPORT
CONFIG_SPL_HASH_SUPPORT
CONFIG_SPL_SHA256

In this example, SHA256 is the only selected hashing algorithm.

And the following booleans:
CONFIG_SPL=y
CONFIG_SPL_DM=y
CONFIG_SPL_LOAD_FIT=y
CONFIG_SPL_FIT=y
CONFIG_SPL_OF_CONTROL=y
CONFIG_SPL_OF_LIBFDT=y
CONFIG_SPL_FIT_SIGNATURE=y

aa9e604410 cmd: eeprom: add support for layout aware commands
Introduce the (optional) eeprom print and eeprom update commands.

These commands are eeprom layout aware:
* The eeprom print command prints the contents of the eeprom in a human
  readable way (eeprom layout fields, and data formatted to be fit for human
  consumption).
* The eeprom update command allows user to update eeprom fields by specifying
  the field name, and providing the new data in a human readable format (same
  format as displayed by the eeprom print command).
* Both commands can either auto detect the layout, or be told which layout to
  use.

New CONFIG options:
CONFIG_CMD_EEPROM_LAYOUT - enables commands.
CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported

Feature API:
__weak int parse_layout_version(char *str)
	- override to provide your own layout name parsing
__weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version);
	- override to setup the layout metadata based on the version
__weak int eeprom_layout_detect(unsigned char *data)
	- override to provide your own algorithm for detecting layout version
eeprom_field.c
	- contains various printing and updating functions for common types of
	  eeprom fields. Can be used for defining custom layouts.

d97dc8a0e6 dm: sata: Separate the non-command code into its own file
At present the SATA command code includes both the command-processing code
and the core SATA functions and data structures.

Separate the latter into its own file, adding functions as needed to avoid
the command code accessing data structures directly.

With this commit:
- All CONFIG option are referenced from the non-command code
- The concept of a 'current SATA device' is confined to the command code

This will make it easier to convert this code to driver model.

At present the SCSI command code includes both the command-processing code
and the core SCSI functions and data structures.

Separate the latter into its own file, adding functions as needed to avoid

new legacy block functions.

- There is no CONFIG option referenced from the command code
- The concept of a 'current SCSI device' is confined to the command code

This will make it easier to convert this code to driver model.
