iucode-tool binary package in Ubuntu Focal amd64

 iucode_tool is a program to manipulate Intel® X86 and X86-64 processor
 microcode collections, and to use the kernel facilities to upgrade the
 microcode on Intel system processors.
 .
 It can load microcode data files in text and binary format, sort, list and
 filter the microcodes contained in these files, write selected microcodes to a
 new file in binary format, or upload them to the kernel.
 .
 It operates on non-free microcode data downloaded directly from Intel or
 installed by the intel-microcode package.
