Marvell has always said they are not interested in having Z1 supported
in mainline, except as a first step to start getting the 375 support in
mainline. I have been waiting for everyone of us to have access to 375
A0 platforms, which is now the case. So I believe we can probably get
rid of the 375 Z1 support entirely.

It saddens me to know that a shiny development board in the office will
no longer be useful for anything else but its own physical beauty, but
I believe that's a normal retirement strategy for a very early
development platform :-)
