cpu_cmd() is reading cpu number via simple_strtoul() which is always
unsigned type.
Platform code implementations are not expecting that nr can be negative
and there is not checking in the code for that too.
This patch is using u32 type for cpu number to make sure that platform
code get proper value range.

The ARM64 has 2 MiB alignment requirement for the kernel. When using
fitImage, this requirement may by violated, the kernel will thus be
executed from unaligned address and fail to boot. Do what booti does
and run booti_setup() for kernel_noload images on arm64 to obtain a
suitable aligned address to which the image shall be relocated.

Add option to the booti_setup() which indicates to it that the caller
requires the image to be relocated to the beginning of the RAM and
that the information whether the image can be located anywhere in RAM
at 2 MiB aligned boundary or not is to be ignored. This is useful ie.
in case the Image is wrapped in another envelope, ie. fitImage and not
relocating it but moving it would corrupt the envelope.

At present the code overruns the bar[] array. Fix this.
At the same time, drop the leading / from the "/spl" path so that we can
run U-Boot SPL with:
spl/u-boot-spl
rather than requiring:
/path/to/spl/u-boot-spl

The current code might succeed on the first allocation and fail on the
second. Separate the checks to avoid this problem.
Of course, free() will never fail and the chances that (when allocating
two small areas) one will succeed and one will fail are just as remote.
But this keeps coverity happy.

There are multiple GPIO banks with up to 32 pins / bank. When
using 'gpio status -a' to read the pins, this patch displays
both GPIO<bank>_<index> similar to how the device trees
display in addition to displaying gpio_#

When CMD_GPIO is enabled the command 'gpio status -a' can cause
a hang or reboot if GPIO banks are not enabled, because it scans
all banks. This patch enables all GPIO banks so 'gpio status -a'

When an exception or interrupt occurs the link register (LR) may
contain the source of the exception, although we do not print the
value it may still be extracted with a debugger. When in SPL we
loop on getting and exception, but use a linking branch, which
over-writes the LR value, use a regular branch instruction here.

This is the case when reading freshly created filesystem.
The error message is like the following:
btrfs_read_superblock: No valid root_backup found!
Since the data from super_roots/root_backups is not actually used -
decided to rework btrfs_newest_root_backup() into
btrfs_check_super_roots() that will only check if super_roots
array is valid and correctly handle empty scenario.
As a result:
* btrfs_read_superblock() now only checks if super_roots array is valid;
the case when it is empty is considered OK.
* removed root_backup pointer from btrfs_info,
which would be NULL in case of empty super_roots.
* btrfs_read_superblock() verifies number of devices from the superblock
itself, not newest root_backup.

avb is_unlocked - check device lock state
avb get_uuid - read and print uuid of a partition
avb read_part - read data from partition
avb read_part_hex - read data from partition and output to stdout
avb write_part - write data to partition
avb verify - run full verification chain

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

Add libavb lib (3rd party library from AOSP), that implements support of
AVB 2.0. This library is used for integrity checking of Android partitions
on eMMC.
libavb was added as it is and minimal changes were introduced to reduce
maintenance cost, because it will be deviated from AOSP upstream in the future.
Changes:
- license headers changed to conform SPDX-style
- avb_crc32.c dropped
- updates in avb_sysdeps_posix.c/avb_sysdeps.h
For additional details check [1] AVB 2.0 README.
