Subject: sandbox: Add generic asm/atomic.h
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=66ff673a8e9f56d2c08a32d12867094c77ea5fd3;p=thirdparty%2Fu-boot.git

sandbox: Add generic asm/atomic.h

In order to compile code that uses <asm/atomic.h> on sandbox, we must
provide this header. RISC-V shows us today how to do so with the generic
header implementation, so copy that.
