Does it use U-Boot or EFI?

• BarsMonster 3y ago
  In kernel config I see: CONFIG_EFI_STUB=y CONFIG_EFI=y If that's what identifies it

    That just defines what the Linux kernel will be able to do, it doesn't necessarily imply that the hardware is using UEFI for firmware to launch another bootloader or OS.

  It can be both - uboot can emulate enough of EFI to start Linux.

  It uses U-Boot, but you can use U-Boot to launch an EFI executable. https://docs.u-boot.org/en/latest/board/thead/lpi4a.html https://docs.u-boot.org/en/latest/board/thead/lpi4a.html https://docs.u-boot.org/en/latest/usage/cmd/bootefi.html https://docs.u-boot.org/en/latest/usage/cmd/bootefi.html

  AIUI Linux boot flow with this SoC goes internal rom -> u-boot SPL --> opensbi --> u-boot --> Linux
