From 99b3d2946253713e8c7aa6544cb9474b0e226843 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 17 Feb 2014 15:23:19 +0100 Subject: ARM: mvebu: rename armada-370-xp.c to board-v7.c In preparation to the introduction of the support of Armada 375 and Armada 38x, this commit renames arch/arm/mach-mvebu/armada-370-xp.c to arch/arm/mach-mvebu/board-v7.c. The board-v7.c name as we expect this file to ultimately contain the DT_MACHINE_START definitions for all ARMv7 Marvell EBU platforms (370, 375, 38x, XP and Dove as of today). In relation to this file rename, this commit also: * Renames the hidden Kconfig symbol MACH_ARMADA_370_XP to MACH_MVEBU_V7. This hidden symbol is selected by the various per-SoC visible Kconfig options to trigger the build of board-v7.c. * Renames a certain number of functions in board-v7.c so that their armada_370_xp prefix is replaced by a mvebu prefix. The .dt_compat array keeps its armada_370_xp prefix because the new SOCs will be introduced with separate .dt_compat arrays, due to the need for different SMP operations.
