lib: sbi_ecall: Remove mcause, scratch and hartid parameters

2020-03-28T08:02:20Z

We remove mcause, scratch and hartid parameters from various functions for ecall handling because we can always get current HART id and current scratch pointer using just one CSR access. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

include: Make sbi_current_hartid() as macro in riscv_asm.h

2020-03-13T06:52:02Z

The sbi_current_hartid() being a regular function is quite expensive because for callers it is a function call instead of a direct CSR read. This patch converts sbi_current_hartid() into a macro in riscv_asm.h. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
