Anup Patel	a3182c91ef	RISC-V: Access CSRs using CSR numbers ... We should prefer accessing CSRs using their CSR numbers because: 1. It compiles fine with older toolchains. 2. We can use latest CSR names in #define macro names of CSR numbers as-per RISC-V spec. 3. We can access newly added CSRs even if toolchain does not recognize newly addes CSRs by name.

Palmer Dabbelt	6d60b6ee0c	RISC-V: Device, timer, IRQs, and the SBI ...

This includes the staticly defined interrupts, the CSR-mapped timer, and virtualized SBI devices. Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>	2017-09-26 15:26:47 -07:00
