-- cgit v1.2.3 From b5ee9002583fc14e6d45a04c18f208987a8fbced Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 5 Sep 2008 21:53:30 -0400 Subject: [ARM] remove a common set of __virt_to_bus definitions Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

Half of the memory is mirrored at 0x00000000 for backwards compatibility. This patch adds the CONFIG_REALVIEW_HIGH_PHYS_OFFSET option option to change the physical base address so that the full amount of RAM is available to Linux. Note that the EB board has 256MB of RAM also mirrored at 0x70000000, the only board without this feature being PB1176.
