Adds support for Cortina Systems Gemini family CPUs: http://www.cortina-systems.com/products/category/18 v3: - fixed __io(a) to be defined as __typesafe_io(a) v2: - #include <asm/io.h> -> <linux/io.h> - remove asm/system.h include - revorked mm.c to use named initializers - removed "empty" dma.h - updated copyrights Signed-off-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt>
