From 865a381223cff0d6d976d9bbe1d57a9288ba147b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 2 Dec 2014 12:54:57 +0100 Subject: [PATCH] ARM: at91: cleanup initilisation code by removing dead code The AT91-specific SoC strucutre "struct at91_init_soc" was filled with specific !DT initilisation functions. Now that we got rid of the !DT board file description, remove unneeded functions.
