This is a quick hack, too trivial to deserve a package.  A more useful
tool would be one that allows you to define named registers and fields
in the various spaces they may exist (memory, I/O, PCI config space,
indirect...).  I've written and used something like that in my day job -
though it wasn't general enough to attempt to release.
