+ Select this to apply patches to the CPU microcode provided by
+ AMD without source, and distributed with coreboot, to address
+ issues in the CPU post production.
+
+ Microcode updates distributed with coreboot are not necessarily
+ the latest version available from AMD. Updates are only applied
+ if they are newer than the microcode already in your CPU.
+
+ Unselect this to let Fam10h CPUs run with microcode as shipped
+ from factory. No binary microcode patches will be included in the
+ coreboot image in that case, which can help with creating an image
+ for which complete source code is available, which in turn might
+ simplify license compliance.
+
+ Microcode updates intend to solve issues that have been discovered
+ after CPU production. The common case is that systems work as
+ intended with updated microcode, but we have also seen cases where
+ issues were solved by not applying the microcode updates.
+
+ Note that some operating system include these same microcode
+ patches, so you may need to also disable microcode updates in
+ your operating system in order for this option to matter.
