lib: Don't return any invalid error from SBI ecall

2020-06-20T05:06:13+00:00

We should only return valid error codes from SBI ecalls as defined by the RISC-V SBI spec. To achieve this: 1. We use SBI_Exxxx defines for OpenSBI internal errors with error values starting from -1000 2. We use SBI_ERR_xxxx defines for errors defined by SBI spec 3. We map some of the SBI_Exxxx defines to SBI_ERR_xxxx defines which are semantically same 4. We throw a error print and force return error code to SBI_ERR_FAILED in sbi_ecall_handler() if we see an invalid error code being returned to S-mode Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Add possible hart status values

2020-02-24T12:41:47+00:00

SBI HSM extension defines possible hart status values in the specification. Define all possible status values. Add a helper function to convert hart state to status because hart states are internal to OpenSBI only and may not match the status values defined in the specification.
