The skipif marker on test_rtc_fast_reg2_execute_violation evaluates
config.getvalue("target"), but in CI pytest is invoked by parametrized
node-id with no --target option, so the predicate is never true and the
test is not skipped on esp32c5/esp32c6/esp32h2/esp32p4. These targets have
no PMS peripheral case for executing from RTC-fast memory, so they raise a
generic "Illegal instruction" panic instead of the "Memory protection
fault" the test expects, and fail on every run.
Replace skipif with the temp_skip marker (already done on master in
288fc561b7). The idf_pytest plugin evaluates temp_skip against the
parametrized target, so these targets are skipped correctly. esp32c3 and
esp32s2 keep running, as they do raise a real memory protection fault.
