Convert the xtensa architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As the generic implementations are
suitable for xtensa this is primarily a matter of moving code.This has only been build-tested, feedback from architecture maintainers
is welcome.Signed-off-by: Paul Burton

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.Suggested-by: Wolfgang Denk

This allows us to use the same DRAM init function on all archs. Add a

This header file is used by three archs. It could be used by all of them
since relocation is a common function. Move it into a generic file.Signed-off-by: Simon Glass

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of . Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.Now all of include directives for are gone.
