 *   @li @e  Microcode Patch Signature @n
 *         Microcode patches are marked by adding a signature before patches in the ROM image to
 *         help identify where they are located.
 *         There're two kind of signatures. One is '$UCODE2K', it indicates there's a following patch with 2K size.
 *         The other is '$UCODE4K', it indicates there's a following patch with 4K size.
 *         If you want to know the patch level / equivalent ID, please consult the BKDG for patch header format.
