How to install Ubuntu on IBM Power 710? [duplicate]

According to the IBM Tech sheet, the IBM Power 710 Express Server uses POWER7+ CPU's.

However, according to both Debian docs and Wikipedia (I'm sure there are other reputable sources as well), the ppc64le architecture is only supported on POWER8 CPU's and later.

This means that Ubuntu (and also Debian) is only supported on systems with at least POWER8 CPU's.
