+ Properties / Entry arguments:
+ - filename: Filename of u-boot-nodtb.bin (default 'u-boot-nodtb.bin')
+ - optional-ucode: boolean property to make microcode optional. If the
+ u-boot.bin image does not include microcode, no error will
+ be generated.
+
+ See Entry_u_boot_ucode for full details of the three entries involved in
+ this process. This entry updates U-Boot with the offset and size of the
+ microcode, to allow early x86 boot code to find it without doing anything
+ complicated. Otherwise it is the same as the u_boot entry.
