lib: utils: Allow PLIC functions to be used for multiple PLICs

2020-05-23T05:06:29Z

We extend all PLIC functions to have a "struct plic_data *" parameter pointing to PLIC details. This allows platforms to use these functions for multiple PLIC instances. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

We can achieve shutdown, cold reboot, and warm reboot using just one sbi_platform callback so we combine system_reboot() and system_shutdown() callbacks into one system_reset() callback. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: No need to provide default PMP region using platform callbacks

2020-04-27T08:27:27Z

The default (usually last) PMP region provides S-mode access to complete memory range not covered by other PMP regions. Currently, the default PMP region is described as platform specific PMP region which is not appropriate because all platforms need it and default PMP region should be part of generic library.

lib: utils: Move PLIC DT fix up codes to fdt_helper.c

2020-03-18T04:10:14Z

Now that we have a dedicated fdt_helper.c file for DT releated helper routines, move plic_fdt_fixup() codes from plic.c to fdt_helper.c and rename it to fdt_plic_fixup() at the same time, to keep name consistency in the same file. Signed-off-by: Bin Meng Reviewed-by: Atish Patra
