  13  * Note: The original firmware from Huawei can only boot 32-bit kernels.
  14  * To boot arm64 kernels it is necessary to flash 64-bit TZ/HYP firmware
  15  * with EDL, e.g. taken from the DragonBoard 410c. This works because Huawei
  16  * forgot to set up (firmware) secure boot for some reason.
  17  *
  18  * Also note that Huawei no longer provides bootloader unlock codes.
  19  * This can be bypassed by patching the bootloader from a custom HYP firmware,
  20  * making it think the bootloader is unlocked.
