Subject: [PATCH 2/8] ARM: at91: cleanup initilisation code by removing dead code
From: Arnd Bergmann <arnd@...db.de>
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.
