This patch series adds support for testing all 4 functions of the HSM extension as defined in the RISC-V SBI specification. The first 2 patches adds some helper routines to prepare for the HSM test, while the third patch adds the actual test for the HSM extension. 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.
