 Hi Mark!

Thanks a lot for the update! If you've got some spare minutes, it would
also be great if you could change the wording of the last two items a
little bit, since this has apparently been written in the very early
days of SLOF and is not up-to-date anymore:

- Instead of "Pseudo Open Firmware", please write "An Open Firmware
implementation" (since most of IEEE1275 has been realized nowadays)

- Instead of " Low Level Firmware for IBM's JS20 (closed source)" please
write: "Low Level Firmware for IBM's JS20, JS21 and the YDL PowerStation
(partially closed source)"

- And maybe add an additional entry like this:
  "Firmware for the emulated 'pseries' machine of QEMU"
