This series add support for the vector crypto extensions:
* Zvkb
* Zvkg
* Zvkh[a,b]
* Zvkn
* Zvksed
* Zvksh

The implementation follows the version 20221220 of the specification,
which can be found here:
  https://github.com/riscv/riscv-crypto/releases/tag/v20221220

Note, that this specification is not frozen yet, meaning that
incompatible changes are possible.
Therefore, this patchset is marked as RFC and should not be considered
for upstream inclusion.

All extensions come with (passing) tests.

A branch with all patches applied can be found in this GitHub repo:
  https://github.com/cmuellner/binutils-gdb/tree/riscv-zvk

Christoph Müllner (6):

Thanks for the patch! actually I've a downstream version for that too,
but apparently isn't as complete as your version (due to lack
testsuite) :P
