5c783b54d6 disk: part_efi: add support to repair gpt table
If a gpt table is corrupted (after a power cut
for example), then the gpt table should repaired.
The function gpt_repair_headers check if at least
one gpt table is valid, and then only write the
corrupted gpt table.

90c52423be lib/date: Make rtc_mktime and mktime64 Y2038-ready
We currently overflow due to wrong types used internally in rtc_mktime,
on all platforms, and we return a too small type on 32-bit.

One consumer that directly benefits from this is mktime64. Many others
may still store the result in a wrong type.

While at it, drop the redundant cast of mon in rtc_mktime (obsoleted by
714209832d).

56717a1388 include: configs: am**x/j721e/j721s2_evm.h: Move the stack pointer init address in arm64
Currently, in case of arm64 bootloader and U-Boot the stack pointer is
initialized at an offset of NON_SECURE_MSRAM_SIZE from arm64 SPL's text
base address. After jumping to arm64, execution is done out of DDR.
Therefore, having an offset corresponding to the size of MSRAM does not
have any significance.

Instead, initialize the stack pointer after an offset of 4MB from the SPL
text base address. This helps in allocating larger memory for stack.

4e65ca00f3 efi_loader: bootmgr: add booting from removable media
Under the current implementation, booting from removable media using
a architecture-specific default image name, say BOOTAA64.EFI, is
supported only in distro_bootcmd script. See the commit 74522c898b
("efi_loader: Add distro boot script for removable media").

This is, however, half-baked implementation because
1) UEFI specification requires this feature to be implemented as part
   of Boot Manager's responsibility:

  3 - Boot Manager
  3.5.1 Boot via the Simple File Protocol
  When booting via the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, the FilePath will
  start with a device path that points to the device that implements the
  EFI_SIMPLE_FILE_SYSTEM_PROTOCOL or the EFI_BLOCK_IO_PROTOCOL. The next
  part of the FilePath may point to the file name, including
  subdirectories, which contain the bootable image. If the file name is
  a null device path, the file name must be generated from the rules
  defined below.
  ...
  3.5.1.1 Removable Media Boot Behavior
  To generate a file name when none is present in the FilePath, the
  firmware must append a default file name in the form
  \EFI\BOOT\BOOT{machine type short-name}.EFI ...

2) So (1) entails the hehavior that the user's preference of boot media
   order should be determined by Boot#### and BootOrder variables.

With this patch, the semantics mentioned above is fully implemented.
For example, if you want to boot the system from USB and SCSI in this
order,
* define Boot0001 which contains only a device path to the USB device
  (without any file path/name)
* define Boot0002 which contains only a device path to the SCSI device,
and
* set BootOrder to Boot0001:Boot0002

To avoid build error for sandbox, default file name "BOOTSANDBOX.efi"
is defined even if it is out of scope of UEFI specification.

edb6982b58 Merge branch '2022-05-02-add-verifying-program-loader'
To quote the author:

U-Boot provides a verified-boot feature based around FIT, but there is
no standard way of implementing it for a board. At present the various
required pieces must be built up separately, to produce a working
implementation. In particular, there is no built-in support for selecting
A/B boot or recovery mode.

This series introduces VPL, a verified program loader phase for U-Boot.
Its purpose is to run the verified-boot process and decide which SPL
binary should be run. It is critical that this decision happens before
SPL runs, since SPL sets up SDRAM and we need to be able to update the
SDRAM-init code in the field.

Adding VPL into the boot flow provides a standard place to implement
verified boot. This series includes the phase itself, some useful Kconfig
options and a sandbox_vpl build for sandbox. No verfied-boot support is
provided in this series.

Most of the patches in this series are fixes and improvements to docs and
various Kconfig conditions for SPL.

8cfac237b9 Merge branch '2022-04-25-initial-implementation-of-stdboot'
To quote the author:
The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.

It introduces the following concepts:

   - bootdev - a device which can hold a distro
   - bootmeth - a method to scan a bootdev to find bootflows (owned by
                U-Boot)
   - bootflow - a description of how to boot (owned by the distro)

This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.

With this we can boot on a Raspberry Pi 3 with just one command:

   bootflow scan -lb

which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.

With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.

...

The design is described in these two documents:

b8aa463e9b bootstd: mmc: Add a bootdev driver
Add a bootdev driver for MMC. It mostly just calls the bootdev helper
function.

Add a function to obtain the block device for an MMC controller.

Fix up the comment for mmc_get_blk_desc() while we are here.

31aefaf89a bootstd: Add an implementation of distro boot
Add a bootmeth driver which handles distro boot from a disk, so we can
boot a bootflow using this commonly used mechanism.

In effect, this provides the same functionality as the 'sysboot' command
and shares the same code. But the interface into it is via a bootmeth.

For now this requires the 'pxe' command be enabled. Future work may tidy
this up so that it can be used without CONFIG_CMDLINE being enabled.

a950d31abe bootstd: Add the bootmeth uclass and helpers
A bootmeth is a method of locating an operating system. For now, just
add the uclass itself. Drivers for particular bootmeths are added later.

If no bootmeths devices are included in the devicetree, create them
automatically. This avoids the need for boilerplate in the devicetree
files.

201417d700 bootstd: Add the bootdev uclass
A 'bootdev' is a device which can be used to boot an operating system.
It is a child of the media device (e.g. MMC) which handles reading files
from that device, such as a bootflow file.

Add a uclass for bootdev and the various helpers needed to make it
work. Also add a binding file, empty for now.

ef5e3891f5 bootstd: Add the bootstd uclass and core implementation
The 'bootstd' device provides the central information about U-Boot
standard boot.

Add a uclass for bootstd and the various helpers needed to make it
work. Also add a binding file.

9d260253e8 bootstd: Add the concept of a bootflow
A bootflow encapsulates the process used to boot an operating system.
It typically has a control file (such as extlinux.conf) and information
about which 'bootdev' it came from.

Add the header file for this first, since it is needed by all other
files.

c24e58f599 fs: Add a function to set the filesystem type
When sandbox is used with hostfs we won't have a block device, but still
must set up the filesystem type before any filesystem operation, such as
loading a file. Add a function to handle this.

4e0710a2d0 dm: core: Allow finding a uclass device by partial name
In some cases two devices are related and the only way to tell is to
check that the names partially patch. Add a way to check this without
needing to create a new string for the comparison.

Fix the comment for device_find_child_by_namelen() while we are here.
