2009-03-24powerpc/86xx: Move gianfar mdio nodes under the ethernet nodesAnton Vorontsov
Currently it doesn't matter where the mdio nodes are placed, but with power management support (i.e. when sleep = <> properties will take effect), mdio nodes placement will become important: mdio controller is a part of the ethernet block, so the mdio nodes should be placed correctly. Otherwise we may wrongly assume that MDIO controllers are available during sleep.

2009-03-24powerpc: setup default archdata for {of_}platform via bus_register_notifierKumar Gala
Since a number of powerpc chips are SoCs we end up having dma-able devices that are registered as platform or of_platform devices. We need to hook the archdata to setup proper dma_ops for these devices. Rather than having to add a bus_notify to each platform we add a default one at the highest priority (called first) to set the default dma_ops for of_platform and platform devices to dma_direct_ops. This allows platform code to override the ops by providing their own notifier call back. In the future to enable >4G DMA support on ppc32 we can hook swiotlb ops.

2009-03-11powerpc/kconfig: Kill PPC_MULTIPLATFORMBenjamin Herrenschmidt
CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
