Subject: [PATCH] asm-generic: define IOMEM for assembly as well
Date: Mon, 9 Jan 2023 18:58:28 +0100 [thread overview]
Message-ID: <20230109175828.2017699-1-ahmad@a3f.at> (raw)
In interest of type safety, we should start using IOMEM() for register
MMIO base addresses that we keep in headers for PBL. Some of these
addresses are used from assembly code as well, so define IOMEM() for
that case.
