From dcea83adc666061864b82c96e059dffe7268b512 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 29 Nov 2008 11:40:28 +0000 Subject: [ARM] Hide ISA DMA API when ISA_DMA_API is unset When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. 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.
