2019-05-17riscv: fix sbi_remote_sfence_vma{,_asid}.Gary Guo1-7/+12
Currently sbi_remote_sfence_vma{,_asid} does not pass their arguments to SBI at all, which is semantically incorrect. Neither BBL nor OpenSBI is using these arguments at the moment, and they just do a global flush instead. However we still need to provide correct arguments.

2017-09-27RISC-V: Device, timer, IRQs, and the SBIPalmer Dabbelt1-0/+100
This patch contains code that interfaces with devices that are mandated by the RISC-V supervisor specification and that don't have explicit drivers anywhere else in the tree. This includes the staticly defined interrupts, the CSR-mapped timer, and virtualized SBI devices. Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>
