From fee04e7f0a6cc45e915b2df4bd3cf07af1a464ec Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Fri, 3 Jan 2014 16:38:07 +0100 Subject: [PATCH 01/32] ARM: mvebu: Makefile clean-up Some objects depend on CONFIG_ARCH_MVEBU whereas this whole Makefile depends on the same symbol. Moreover CONFIG_ARCH_MVEBU can't be selected as a module. So we can simplify this Makefile by moving all the object from obj-$(CONFIG_ARCH_MVEBU) to obj-y.

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.

The Armada 380 is a single core Cortex-A9, while the Armada 385 is a dual-core Cortex-A9. The support is introduced in board-v7.c, together with Armada 370/XP, but a separate DT structure is added, because Armada 38x will need a different set of SMP operations when the SMP support is introduced.

In order to help Debian transition between mach-kirkwood and mach-mvebu, the DTS files are compiled for both, allowing Debian to continue using mach-kirkwood until all remaining boards are supported by mach-mvebu. Debian is then expected to simply swap from mach-kirkwood to mach-mvebu and mach-kirkwood will be removed.

We're also migrating DT kirkwood boards into mach-mvebu. The kirkwood changes make the different SoCs in mach-mvebu/ depend on MULTI_V7 or MULTI_V5 as appropriate. We add this dependency to the new SoCs so that when the branches are merged, everything is as it should be.
