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