# Makefile for Ampere Jade.

# This is only partially done. It is derived from other ARM

# The goal is to create a kernel we can start from the UEFI shell. At present,
|
|
# when we do this, we get this:
|
|
# FS3:\EFI\opensuse\> Image
|
|
# EFI stub: Booting Linux Kernel...
|
|
# EFI stub: Generating empty DTB
|
|
# EFI stub: Exiting boot services and installing virtual address map...
