cr50: add plumbing for signing CR50 RO images
The signer utility needs to be built and the flat image needs to be
signed. The signer utility is written in C++, supporting this required
adding a new make command to Makefile.rules and a build file for the
utility.
The signing now needs to be a part of generating the .flat file. To
achieve this an alternative set of rules is defined in Makfile.rules
for targets where RO image needs to be signed.
Rules for converting elf to hex have been consolidated as there is no
need to omit the --set-section-flags when it does not apply.
BRANCH=none
BUG=chrome-os-partner:43025
TEST=as follows:
- ran 'rm build/cr50; make BOARD=cr50'
- observed that both build/cr50/ec.bin and
build/cr50/RO/ec.RO.flat have the required signature header in
the first 1024 bytes.
- verified that the cr50 board can be booted over SPI using the
image in build/cr50/RO/ec.RO.flat
