The SoC looks for two RO images at reset, and is typically
configured for two RW images as well. This CL reports version
strings for all those images, as well as identifying the active
RO and RW copies.
Since the RO image doesn't contain a version string, we create
one using the epoch_, major_, minor_, and img_chk_ members of its
signed header.
BUG=chrome-os-partner:55558
BRANCH=none
TEST=make buildall; run on Cr50 hardware
The "version" command now includes information like this:
RO_A: * 0.0.2/a3c3d5ea
RO_B: 0.0.2/8895c9eb
RW_A: cr50_v1.1.4965-a6c1c73-dirty
RW_B: * cr50_v1.1.4959-2f49d5c
The '*' indicates the active image.
The test/tpm_test/tpmtest.py program has been updated to request
the version information at startup, and it also now reports
similar information, just all on one line:
RO_A:* 0.0.2/a3c3d5ea RO_B: 0.0.2/8895c9eb RW_A: cr50_v1.1 ...
The active images are marked with a '*' following the ':', so
that the same regexp can match either format:
($ro, $rw) = m/RO_[AB]:\s*\*\s+(\S+).*RW_[AB]:\s*\*\s+(\S+)/s;
