Extend test_arm_raspi4_initrd to exercise the RNG200 and thermal
sensor devices added in this series: confirm the RNG200 driver probes
it ("hwrng registered" in the kernel log), then once at a shell
confirm the thermal zone reports the expected fixed reading and that
/dev/hwrng actually yields data rather than just existing.These checks go into the existing initrd boot test rather than a new test, to avoid spending test time booting the same kernel again. Verified locally against this series with the exact kernel/initrd assets this file already pins.
