define Package/memtest86plus/description
  Memtest86+ is a free, open-source, stand-alone memory tester for x86
  architecture computers. It provides a much more thorough memory check
  than that provided by BIOS memory tests. It is also able to access
  almost all the computer's memory, not being restricted by the memory
  used by the operating system. It should work on most x86 CPUs
  (Pentium class or later 32-bit).

  This package adds approx 153 kB to the kernel partition.

define Package/memtest86plus-efi/description
  Memtest86+ is a free, open-source, stand-alone memory tester for x86-64
  and LoongArch64 architecture computers. It provides a much more thorough
  memory check than that provided by BIOS memory tests. It is also able to
  access almost all the computer's memory, not being restricted by the memory
  used by the operating system and not depending on any underlying software
  like UEFI libraries. It should work on most x86-64 CPUs and most LoongArch64
  CPUs (Loongson 3 and Loongson 2 family).

  This package adds approx 154 kB to the kernel partition.
