Subject: [PATCH v2 03/33] locking/atomic: h8300: use asm-generic exclusively
Date:   Tue, 25 May 2021 15:02:02 +0100
Message-Id: <20210525140232.53872-4-mark.rutland@arm.com>
In-Reply-To: <20210525140232.53872-1-mark.rutland@arm.com>
References: <20210525140232.53872-1-mark.rutland@arm.com>
Precedence: bulk

As h8300's implementation of the atomics isn't using any arch-specific
functionality, and its implementation of cmpxchg only uses assembly to
non-atomically swap two elements in memory, we may as well use the
asm-generic atomic.h and cmpxchg.h, and avoid the duplicate code.
