Subject: [PATCH v2 30/34] ARM: mmu32: move functions into c file
Date: Wed, 17 May 2023 11:03:36 +0200	[thread overview]
Message-ID: <20230517090340.3954615-31-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230517090340.3954615-1-s.hauer@pengutronix.de>

Move create_flat_mapping() and create_sections() into the c file
rather than having them as static inline functions in the header file.

Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
