Sascha Hauer 9fe8679d3b debug_ll: Let architectures define PUTC_LL directly 
putc already is a regular barebox function. To avoid conflicts and
confusions just let architectures define PUTC_LL directly instead
of going through this addiotional redirection.

Sascha Hauer 77322aa896 Treewide: remove address of the Free Software Foundation 
The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

Sascha Hauer dd3c898d06 Merge branch 'for-next/dma-cache-align' 2012-07-02 10:59:22 +02:00
Marc Kleine-Budde ed2180d658 blackfin, mips, openrisc, ppc, sandbox, x86: add generic dma_alloc, dma_free inlines 
Some drivers call dma_inv_range() on buffers, on arm these buffers must
be cache line aligned. This patch introduces a generic dma_alloc,
dma_free. Archs can implement in their own functions in "asm/dma.h" and add a:

	#define dma_alloc dma_alloc
	#define dma_free dma_free

On all other archs the generic versions, which translate into xmalloc
and free are used.
