Subject: [RFC 07/13] arm64: Mark ARCH_MVEBU as needing broken 64bit MMIO support
Date: Fri, 26 Feb 2021 15:02:59 +0100 [thread overview]
Message-ID: <20210226140305.26356-8-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20210226140305.26356-1-nsaenzjulienne@suse.de>
The bus AP806's IOMMU sits on can't handle 64bit MMIO accesses[1]. So
select 'ARCH_HAS_64BIT_MMIO_BROKEN' for the platform.
Signed-off-by: Nicolas Saenz Julienne <nsaenzjulienne@suse.de>
[1] See Armada-AP806 erratum #582743
