lib: sbi: Update pmp_get() to return decoded size directly

2020-03-18T03:28:26Z

Currently pmp_get() returns the log2 length of the PMP memory region size. The caller has to calculate the size based on that and the same codes are duplicated. Update this function to return decoded size directly. Signed-off-by: Bin Meng Reviewed-by: Atish Patra

Revert "lib: Use __builtin_ctzl() in pmp_get()"

2020-02-18T03:58:33Z

This reverts commit 897b8fbdd92fcfad194417d348b8dad16ab0e17a. We are seeing compile errors using newlib based GCC cross-toolchain so we restore back old ctz() implementation. Signed-off-by: Anup Patel

lib: Fix CPU capabilities detection function

2019-11-26T10:36:29Z

On some platforms, misa may not be implemented. On such a platform, reading misa will get 0. At this time, platform is required to implement a non-standard function to detect the CPU's capabilities. Therefore, this modification add interfaces for non-standard function. The MXL field of misa is always at the highest two bits, whether it is a 32-bit 64-bit or a 128-bit machine. Therefore, this modification fixes the use of a fixed offset to detect the machine length. Signed-off-by: Xiang Wang Signed-off-by: Anup Patel
