# This is the makefile for a flash image, a netbootable sshd image,
# and a netbootable cpu image.
#
# sshdkernel produces a kernel with a built-in initramfs for netboot
# It provides (and starts) an sshd, and also has flashrom.
# Hence you can ssh to a node, flashrom -r on it, scp the
# image back, process it, scp the new image to the node, and
# write with flashrom.
# e.g.
# ssh -i class_key -p 2022 board flashrom -r image.bin -p internal
# scp -i class_key -P 2022 board:/image.bin image.bin
# make tiny.bin
# scp -i class_key -P 2022 tiny.bin board:/tiny.bin
# ssh -i class_key -p 2022 board flashrom -w tiny.bin -p internal
#
# The cpu image uses a cpud as its init, and you
# can cpu to it to run commands, including flashrom -p internal
# to flash the flash image.
# e.g.
# cpu board flashrom -r image.bin -p internal
# Note this writes image image.bin to the host directoy; no scp needed
# make tiny.bin
# cpu board flashrom -w tiny.bin -p internal
# cpu is way more convenient than ssh/scp if you can learn it.
# you can also just
# cpu board
# and once you are in:
# flashrom -r image.bin -p internal
# make tiny.bin
# flashrom -w tiny.bin -p internal
# NOTE: those commands are running on the board, and they all work
#
# You can test the flash image kernel with qemu
# make flashtest

# sshdkernel and cpukernel are very similar,
# so doing builds in this order minimizes kernel
# change between them.
