Subject: [PATCH 0/6] add ima_arch support for ARM64

Add IMA arch dependent support for ARM64. Some IMA functions can check
arch-specific status before running. For example, the ima_load_data
function or the boot param "ima_appraise=" should not be executed when
UEFI secure boot is enabled. We want to fill the gap in order to complete
the IMA support on ARM64.

Chester Lin (6):
  efistub: pass uefi secureboot flag via fdt params
  efi/arm: a helper to parse secure boot param in fdt params
  efi: add secure boot flag
  efi/arm: check secure boot status in efi init
  arm64/ima: add ima arch support
  docs/arm: add the description of uefi-secure-boot param
