+# 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
