From 6d31727a0b6fe7206725c93508e6d2065f16ff03 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Mon, 13 May 2013 19:32:14 +0000 Subject: ARM: Orion: Remove redundant init_dma_coherent_pool_size() The patch: 387870f mm: dmapool: use provided gfp flags for all dma_alloc_coherent() calls makes these calls on Kirkwood and Orion5x redundant. The drivers are not making atomic requests for coherent memory and hence the default pool size is now sufficient. Jason Cooper added mach-mvebu/ hunk, and corrected minor typos in commit message.

This makes the description of the hardware incomplete, for it lacks the Device Bus childs address space. In order to fix this, it's required to add a 'ranges' entry with a suitable address space to map Device Bus childs, on a per-board basis. This patch fixes the ranges property on the Armada XP GP board.

In the same time Rob Herring moved the ARCH_MVEBU block to arch/arm/mach-mvebu/Kconfig with this commit and also merged in 3.7: 387798b ARM: initial multiplatform support Unfortunately the ARCH_REQUIRE_GPIOLIB have been lost during this migration. This was not noticed until the v3.10-rc1, because mvebu as part of ARCH_MULTIPLATFORM was always selected with ARCH_VEXPRESS, and this architect selected ARCH_REQUIRE_GPIOLIB. Since the following commit from Arnd: "883a106 ARM: default machine descriptor for multiplatform", ARCH_VEXPRESS was then no more selected by default with ARCH_MVEBU and it made appeared the lack of ARCH_REQUIRE_GPIOLIB for mvebu. This commit added back the selection of ARCH_REQUIRE_GPIOLIB for ARCH_MVEBU.

However, beyond just the register areas, there are also PCIe I/O and memory regions, whose addresses should be properly translated. This patch fixes the Armada 370 and XP ranges property to take PCIe into account properly.
