From 8d39e0fd080fbc2287bca3f596741a38281634da Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Thu, 16 Aug 2012 17:36:55 +0800 Subject: arm: at91: use macro to declare soc boot data Instead of check the pointer of the init function, check the new builtin bool to known if the soc is enabled. This is needed as with the switch to the pinctrl the init will be NULL on pure DT SoC.
