lwip: provide a sntp_format_time() function

2025-08-01T07:30:47+00:00

Provide a trivial implementation of sntp_format_time() to fix a build
error when CONFIG_LWIP_DEBUG=y:

lib/lwip/lwip/src/apps/sntp/sntp.c: In function ‘sntp_format_time’:
lib/lwip/lwip/src/apps/sntp/sntp.c:283:10: error: implicit declaration of function ‘ctime’ [-Werror=implicit-function-declaration]
  283 |   return ctime(&ut);
      |          ^~~~~

efi_loader: add missing check in FMP.GetImageInfo()

2025-07-26T05:37:03+00:00

The UEFI 2.11 specification, chapter 23.1.3 requires
EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo() to return
EFI_INVALID_PARAMETER if *ImageInfoSize is not too small
and ImageInfo is NULL.

efi_selftest: fix ESRT creation tests

2025-07-26T05:37:03+00:00

The code foresees that parameters descriptor_size and descriptor_count
might be NULL and then dereferences them without further check.

The size check must take into account the descriptor count.

ImageInfo might be NULL. In this case we must not dereference it.

efi_loader: correct EFI_DEBUG_TABLE_ENTRY_SIZE

2025-07-26T05:37:03+00:00

With the current code we allocate to little memory when adding entries to
the EFI_DEBUG_INFO_TABLE and we fail to correctly move entries when an
entry is removed.

EFI_DEBUG_TABLE_ENTRY_SIZE must be the size of an entry in the
EFI_DEBUG_INFO_TABLE, not the size of a pointer.

efi: Create a new CONFIG_EFI

2025-07-26T05:34:31+00:00

Create a Kconfig which indicates that EFI functionality is in use,
either as a client (EFI app / stub) or provider (EFI loader). This will
make it easier to share code between these two parts of U-Boot

efi: Rename CONFIG_EFI to CONFIG_EFI_CLIENT

2025-07-26T05:34:28+00:00

The generic name 'EFI' would be more useful for common EFI features. At
present it just refers to the EFI app and stub, which is confusing.

Rename it to EFI_CLIENT

efi: Rename the lib/efi directory

2025-07-26T05:29:31+00:00

This directory was created when U-Boot gained the ability to run as an
EFI app in 2015. Since then the EFI-loader feature has been added.

The code in lib/efi is not actually used by the loader, so the name is
confusing.

Rename the directory to efi_client to indicate that it includes files
just for U-Boot being a client of EFI, i.e. the EFI app and stub.
