ARM: dts: Disable MDMA1 node for Arndale-octa board
MDMA1 can support both secure and non-secure AXI transactions. When this is enabled in the kernel for boards that run in secure mode, we get imprecise external aborts causing the kernel to oops. Unhandled fault: imprecise external abort (0x1406) at 0x00000000 Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000007 Signed-off-by: Tushar Behera <tushar.behera@linaro.org> Conflicts: arch/arm/boot/dts/exynos5420-arndale-octa.dts
