Subject: [PATCH 2/7] ARM: <asm/io.h>: define macros for I/O memcpy/memset
Date: Tue, 2 Feb 2021 20:40:54 +0100 [thread overview]
Message-ID: <20210202194059.9466-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210202194059.9466-1-a.fatoum@pengutronix.de>
<asm-generic/io.h> expects architectures to define memcpy_toio,
memcpy_fromio and memset_io as macros as it checks for their existence
with #ifndef. Only ARM defines an own implementation, but does so
as function declaration. Add the missing macros.
