From c750815e2d436f4379c7af8a8770ef2ae71c5607 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 26 Oct 2008 10:55:14 +0000 Subject: [ARM] Arrange for platforms to select appropriate CPU support Rather than: config CPU_BLAH bool depends on ARCH_FOO || MACH_BAR default y if ARCH_FOO || MACH_BAR arrange for ARCH_FOO and MACH_BAR to select CPU_BLAH directly.

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.
