This bintool wraps the `softhsm2-util` command shipped with SoftHSMv2 (a
software implementation of a PKCS#11 token). Binman uses this wrapper only
to check that softhsm2-util is installed (and to fetch it if missing); any
actual token initialisation or key import for signing FIT images or
capsules is done outside binman, typically via mkimage and the OpenSSL
PKCS#11 engine.
See https://www.opendnssec.org/softhsm/ for more details.
