Subject: [PATCH 13/21] iommu/mediatek: Make MTK_IOMMU depend on ARM64
Date: Sat, 11 Jul 2020 14:48:38 +0800 [thread overview]
Message-ID: <20200711064846.16007-14-yong.wu@mediatek.com> (raw)
In-Reply-To: <20200711064846.16007-1-yong.wu@mediatek.com>
Originally MTK_IOMMU could depend on ARM || ARM64.
Both build ok. actually the source code don't support ARM.
this patch changes it only depend on ARM64.
This is a preparing patch for support multi-domain.
otherwise it will build warning in ARM case.
This is the build warning log:
drivers/iommu/mtk_iommu.c:163:27: note: in expansion of macro 'SZ_4G'
{.iova_base = 0, .size = SZ_4G},
include/uapi/linux/const.h:20:19: warning: large integer implicitly truncated
to unsigned type [-Woverflow]
#define __AC(X,Y) (X##Y)
^
include/uapi/linux/const.h:21:18: note: in expansion of macro '__AC'
#define _AC(X,Y) __AC(X,Y)
^
include/linux/sizes.h:46:18: note: in expansion of macro '_AC'
#define SZ_4G _AC(0x100000000, ULL)
