[PATCH v4 0/3] RISC-V: Support more rigorous check for CSR

[Nelson Chu]

Hi binutils,

Updated.  Since I extend the DECLARE_CSR to record more informaton, riscv-gdb
also need to be updated.  Therefore, I send these patches to gdb-patches mail
list and wait for approval, too.

* [PATCH v4 1/3] RISC-V: Support the ISA-dependent CSR checking.
1. Add missing comments for each function.
2. Add -march=rv32if option to the csr-dw-regnum test case.
3. Report warning messages rather than error for the CSR cheking.

* [PATCH v4 2/3] RISC-V: Disable the CSR checking by default.

* [PATCH v4 3/3] RISC-V: Support the read-only CSR checking.

Thanks
Nelson
