Subject: [PATCH] ARM: dts: exynos5422-odroidxu3: reduce total RAM by 22 MiB
Date: Wed, 21 Jan 2015 13:22:52 +0100	[thread overview]
Message-ID: <1421842972-25807-1-git-send-email-m.szyprowski@samsung.com> (raw)

Last 22 MiB is RAM is reserved by secure monitor code and cannot be
accessed from Linux kernel, so adjust total RAM size to 0x7EA00000
(2 GiB - 22 MiB). This fixes random 'imprecise kernel abort' kernel
failures.
