The shortlog from the vendor tool's automated patch is reproduced at
the bottom of this commit message.
The automated commit is squashed with one to update how we depend on
bus parameters. Before, we had to provide an "Ibex top package". This
behaved the same as OpenTitan's "lowrisc:constants:top_pkg", but
avoided having to vendor in that file.
On the OpenTitan side, this has been tidied up with commit
d266c68 ("[dv] Update dv_utils sources to use bus_params_pkg"). This
changes the dependency of dv_utils to
"lowrisc:opentitan:bus_params_pkg". We still have to provide our
own (now called "lowrisc:ibex:bus_params_pkg") and need to patch the
dv_utils dependency, but this is a bit cleaner because dv_utils is
less likely to accidentally include dependencies on OpenTitan
internals.
On our side, we have to update the vendoring patch for dv_utils (and
change its name). We also need an equivalent patch for dv_lib. Then we
rename our hacky "Ibex top package" to "bus_params_pkg". The ICache DV
environment also needs patching to use the bus parameters properly.
Phew!

Bus parameters for DV utilities
The Ibex DV code uses a dv_utils support library vendored from
OpenTitan. This library needs some basic parameters: things like
bus address and data widths and similar.
The dv_utils library is supposed to be parametric, in that it should
work with any such widths, but a project that imports the library
needs to supply them in a SystemVerilog package called
bus_params_pkg. This directory contains that package, which can be
imported with the fusesoc core lowrisc:ibex:bus_params_pkg.
