This is a 'semi official' utility script which re-signs previously
generated CR50 RW images.
By default the script uses ec.RW.elf and ec.RW_B.elf in build/cr50/RW
as inputs and util/signer/ec_RW-manifest-dev.json as the manifest, and
places the newly signed images into build/cr50/ec.bin.
The only outside dependency of this script is the signing utility itself,
which is expected to be available as $HOME/bin/codesighner.
The following command line options are accepted:
b1 - generate signature for the b1 version of the H1 chip
elves <elf1> <elf2> - sign the supplied elf files instead of the
default ones. Handy if the builder generated files need to be
signed
help - print this message
hex - generate hex output instead of binary
prod - sign with prod key (no debug image will be signed)
When invoked with 'hex' as a command line parameter, the script just
re-signs the supplied elf files and places them in 0.signed.hex and
1.signed.hex in the current directory.
This script also allows to sign dev images for running on prod RO. To
do that invoke this script as follows:
H1_DEVIDS='<dev id0> <dev id1>" ${progname} [other options, if any]
where <dev id0> <dev id1> are values reported by sysinfo command in the
DEV_ID: line when ran on the CR50 for which the image is built.

TEST=manual
tried signing dev and prod images, including sighing a dev image to
run on a prod device. All cases succeeded.
