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 :-) Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
