[PATCH v10 04/16] target/riscv: Add x-zba, x-zbb, x-zbc and x-zbs properties |
Date: |

The bitmanipulation ISA extensions will be ratified as individual
small extension packages instead of a large B-extension. The first
new instructions through the door (these have completed public review)
are Zb[abcs].
This adds new 'x-zba', 'x-zbb', 'x-zbc' and 'x-zbs' properties for
these in target/riscv/cpu.[ch].

(no changes since v3)
Changes in v3:
- Split off removal of 'x-b' property and 'ext_b' field into a separate
patch to ensure bisectability.
