From 0387848b1b2a726581536234c770fbabe7290354 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Thu, 5 Mar 2015 20:19:36 -0500 Subject: [PATCH] ARM: PSCI: Rework the DT handler slightly The way the PSCI DT update happens currently means we pull in everywhere, including on ARMv8 and that in turn brings in for some non-PSCI related things that header needs to deal with. To fix this, we rework the hook slightly. A good portion of arch/arm/cpu/armv7/virt-dt.c is common looking and I hope that when PSCI is needed on ARMv8 we can re-use this by and large. So rename the current hook to psci_update_dt(), move the prototype to and add an #ifdef that will make re-use later easier.
