Well, I think, Sascha is right, we have to fix
arch/arm/plat-mxc/include/mach/dma-mx1-mx2.h, because that's what actually
got broken. The line
#define DMA_BASE IO_ADDRESS(DMA_BASE_ADDR)
in it is no longer valid, right? So, we have to either remove it, or fix
it, if we think, that other drivers might start using it. And even if we
decide to remove it from the header and implement here, wouldn't it be
better to choose a name, not beginning with "__"? Something like
MX1_DMA_REG, perhaps? Or maybe even we shall remap those registers?
Thanks
