I implemented the UEFI Specification version 2.10, specifically focusing on
the functionality described in Section 18.4, which details the EFI Debug
Support Table feature. This implementation ensures support for
hardware-assisted debugging and provides a standardized mechanism for
debuggers to discover and interact with system-level debug resources.

V2: add Kconfig options to turn on/off this feature.
V3: Fix the way of removing debug_image_info.
V4: Fix efi_realloc return failure code and efi_alloc_aligned_pages() for
    system_table_pointer.
V5: Fix function comments and move the code into a separate module.

Ying-Chun Liu (PaulLiu) (4):
  efi: add EFI_SYSTEM_TABLE_POINTER for debug
  efi: add EFI_DEBUG_IMAGE_INFO_TABLE for debug
  lib: efi_loader: efi_memory.c: add efi_realloc() for realloc memory
  efi: add EFI_DEBUG_IMAGE_INFO for debug
