This commit was generated by running
for hj in $(grep -l opentitan vendor/*.vendor.hjson); do
$opentitan/util/vendor.py -U -c $hj
done
and then squashing together all the resulting commits. It will be
followed by a patch that combines these vendor.hjson files (using the
vendor tool's new "mapping" functionality), but we need a patch first
to get everything in sync before squashing together.

Ibex RISC-V Core
Ibex is a small and efficient, 32-bit, in-order RISC-V core with a 2-stage pipeline that implements the RV32IMC instruction set architecture.
Ibex offers several configuration parameters to meet the needs of various application scenarios. The options include two different choices for the architecture of the multiplier and divider unit, as well as the possibility to drop the support for the "M" extension completely. In addition, the "E" extension can be enabled when opting for a minimum-area configuration.
This core was initially developed as part of the PULP platform under the name "Zero-riscy" [1], and has been contributed to lowRISC who maintains it and develops it further. It is under active development, with further code cleanups, feature additions, and test and verification planned for the future.
Documentation
The Ibex user manual can be
read online at ReadTheDocs. It is also contained in
