From c19aa754f32ff1dd7cb8e96454f5eba95c20585e Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Mon, 30 Apr 2007 17:15:46 +0200 Subject: [AVR32] Use correct config symbol when setting cpuflags As Robert P. J. Day pointed out, the CONFIG_CPU_AT32AP7000 symbol wasn't used for anything. It should have been used to select the correct -mcpu= options for CFLAGS. -mcpu=ap7000 is the default anyway, so this patch shouldn't really make any difference, but it's always nice to do things correctly.

These will do basically the same thing as dma_alloc_coherent() except that the virtual mapping will allow write buffering, causing better performance for certain use cases like frame buffers. The same API is already available on ARM.
