From 136dfa5edae3207422a8b93347eb79e92e07cdfa Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 3 Sep 2013 11:32:24 +0200 Subject: ARM: delete mach-shark The Shark machine sub-architecture (also known as DNARD, the DIGITAL Network Appliance Reference Design) lacks a maintainer able to apply and test patches to modernize the architecture. It is suspected that the current kernel, while it compiles, does not even boot on this machine. The listed maintainer has expressed that he will not be able to spend any time on the maintenance for the coming year. So let's delete it from the kernel for now. It can always be resurrected with git revert if maintenance is resumed. As the VIA82c505 PCI adapter was only used by this architecture, that gets deleted too.
