The HS ucode runs on PMU with all interrupts disabled. So it will not be able to detect any data corruption introduced in the IMEM or DMEM due to bit flips. In order to mitigate this issue validate the integrity of IMEM and DMEM at the end of HS ucode bootstrap and fail the boot incase of any un-corrected errors.
