The following patches include implementing hotplug with ATCSMU deep sleep mode
using HSM extension, introduce ATCSMU system device and some fixes, base on
OpenSBI v1.2 and test on AE350 platform with the CPU listed below:
RV64:
* AX45MP quad-core
* AX45MP octa-core
* AX25MP quad-core
RV32:
* A45MP quad-core
* A25MP quad-core
Changes v1 -> v2:
* Drop patch for adding secondary_boot callback
* Add a PATCH4 to move ATCSMU related code to lib/utils/sys
* Include RB tags
Changes v2 -> v3:
* Refine PATCH4 suggested by Anup [1]
* Remove redundant headers
* Move is_andes25() to ae350.c
* Add "struct smu_data *smu" parameter to each smu related functions
* Refine PATCH6 suggested by Anup [2]
* Make FDT_RESET_ATCWDT200 depends on SYS_ATCSMU
* PATCH5 & PATCH6: Instantiate struct smu_data in ae350.c and fdt_reset_atcwdt200.c
