It doesn't really matter precisely what a BOGOMIP is, except to say that

Bogomips are used for micro timings in some device drivers. I don't think they are
used for any other purpose. Mostly this is for devices with funny timing
characteristics such as not accepting a second command for a short period after
getting a first command.
