From 1e6cbc0691abc6b1a053f98d8ce1d692c8c71501 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 20 Jun 2016 22:27:23 +0200 Subject: ARM: ux500: move l2x0 init to .init_irq The generic IRQ init function also enables the l2 cache implicitly when the machine descriptor sets an .l2c_aux_mask. Let's use that on ux500 and remove the ux500_l2x0_init() along with the cpu_is_u8500_family checks.
