lib: Remove target_hart and hartid parameter from TIMER callbacks

2019-01-23T03:09:26Z

The target_hart and hartid paramter of TIMER callbacks is not required because it always current hartid which can be obtained using sbi_current_hartid() API. Signed-off-by: Anup Patel

lib: Remove source_hart and hartid parameter from IPI callbacks

2019-01-23T03:09:26Z

The source_hart and hartid parameter is really not required in IPI callbacks of sbi_platform because current hartid can always be obtained by calling sbi_current_hartid() API. Signed-off-by: Anup Patel

lib: Redirect illegal instruction trap to S-mode when not handled

2018-12-31T03:58:26Z

Currently, we fail with error SBI_ENOTSUPP when we are not able to handle illegal instruction trap. Instead, we should just redirect illegal instruction trap to S-mode when not handled. This redirection of illegal instruction trap will help lazy save/restore of floating point registers to work correctly in Linux kernel. Signed-off-by: Anup Patel

lib: Print mtval in sbi_trap_error()

2018-12-27T04:36:38Z

The mtval CSR is very useful information when debugging hence print it upon trap error in sbi_trap_error(). Signed-off-by: Anup Patel

lib: Add misaligned load/store trap handling

2018-12-26T05:44:22Z

We generally don't get misaligned load/store traps from Linux/U-Boot compiled using GCC 8.2 or higher but this is not true with older GCC toolchains. To tackle this we add misaligned load/store trap handling adopted from BBL sources but much more simpler. (Note: BBL sources can be found at https://github.com/riscv/riscv-pk.git) Signed-off-by: Anup Patel

Introduce sbi_current_hartid()

2018-12-21T08:06:59Z

Use this helper instead of hardcoding csr_read(mhartid). Signed-off-by: Damien Le Moal
