[U-Boot] [PATCH 0/4] Rationalise atomic.h implementations

This series applies on top of https://patchwork.ozlabs.org/patch/958286/

The intention is to rationalise most of the current implementations of atomic.h. x86 remains as having an arch specific implementation which I don't intend to touch.

Chris Packham (4): Add include/asm-generic/atomic.h ARM: use asm-generic/atomic.h mips: use asm-generic/atomic.h xtensa: use asm-generic/atomic.h
