From e1bbb55d11622012197a654af874f9f485ddbc47 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 9 Aug 2012 17:10:36 +0200 Subject: ARM: ux500: reform Ux500 family names Counting the U9540 and the new U8540 as a U8500 family member does not work. Instead, split the function in two: cpu_is_u8500_family() covering U8500 and U8520 cpu_is_ux540_family() covering U9540 and U8540 This works much better in practice. Update users to keep the same behaviour.
