This patch series adds support for testing all 4 functions of the HSM extension as defined in the RISC-V SBI specification. The first 4 patches add some helper routines to prepare for the HSM test, while the last patch adds the actual test for the HSM extension. v5: - Addressed all of Andrew's comments. - Added 2 new patches to clear on_cpu_info[cpu].func and to set the cpu_started mask, which are used to perform cleanup after running the HSM tests. - Added some new tests to validate suspension on RV64 with the high bits set for suspend_type. - Picked up the hartid_to_cpu rewrite patch from Andrew's branch. - Moved the variables declared in riscv/sbi.c in patch 2 to group it together with the other HSM test variables declared in patch 5. v4: - Addressed all of Andrew's comments. - Included the 2 patches from Andrew's branch that refactored some functions. - Added timers to all of the waiting activities in the HSM tests. v3: - Addressed all of Andrew's comments. - Split the report_prefix_pop patch into its own series. - Added a new environment variable to specify the maximum number of CPUs supported by the SBI implementation. v2: - Addressed all of Andrew's comments. - Added a new patch to add helper routines to clear multiple prefixes. - Reworked the approach to test the HSM extension by using cpumask and on-cpus.
