Subject: [U-Boot] [PATCH v2 12/12] sunxi: Add limit with the MMC environment
Date: Tue, 16 Jan 2018 09:44:24 +0100 [thread overview]
Message-ID: <20180116084424.17801-13-maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <20180116084424.17801-1-maxime.ripard@free-electrons.com>
The MMC environment offset is getting very close to the end of the U-Boot
binary now. Since we want to make sure this will not overflow, add a size
limit in the board for arm64. arm32 has already that limit enforced in our
custom image generation.
