[PATCH v3 0/2] RISC-V: Add preliminary textra trigger CSR functions

[Alvin Chang]

According to RISC-V Debug specification, the optional textra32 and textra64
trigger CSRs can be used to configure additional matching conditions for the
triggers.

This series support to write MHVALUE and MHSELECT fields into textra32 and
textra64 trigger CSRs. Besides, the additional matching condition between
textra.MHVALUE and mcontext CSR is also implemented.

Changes from v2:
- Remove redundant log

Changes from v1:
- Log that mhselect only supports 0 or 4 for now
- Simplify writing of tdata3
