The update_firmware script is intended to update the boot firmware but the details including the offset and hardware partition are dependent on the boot device. Specifically: - IMX8MM/IMX8MP (BOOTROM v2) the offset is 32KiB for SD and eMMC user hardware partition and 0KiB for eMMC boot partitions. - IMX8MM the offset is 33KiB for SD and eMMC regardless of hardware partition. Dynamically set soc, dev, bootpart, and bootblk env vars at runtime and use these in the update_firmware script. Remove the splblk env var from config files as its no longer needed.
