This was due to the existance of inter-connect clocks which weren't associated with any physical device and thus could not be handled (think get, enable, disable) correctly. As a consequence the platform would catastrophically fail when the Common Clock Framework tried to disable unused clocks. Now we do have critical-clock support, it has identified some additional clocks which are required for the successful functioning of some key IP. With the introduction of critical-clock support in v4.8, our developers' default configuration is to run with 'clk_ignore_unused' removed. This patch-set ensures they can achieve successful boot when a) booting from an SD Card and when b) booting using USB->Eth adaptors for NFS booting. Please consider this set for your respective -fixes branches for inclusion into the v4.8-rcs.
