I don't want to sound picky here but ...

it is not just similar to an ARM -- it is an ARM from
a specific vendor and with specific features.  That
makes it a CPU model within the ARM family. 

So it is a new BSP and possibly what we call "new in
family" which means you might have some tweaking
to do to code outside the BSP to handle a different
CPU core.

A port is to a new architecture entirely.  Think
mips versus powerpc versus arm.
