Change Details

This patch introduces a function that adds missing arm,io-coherent property to Marvell Armada 38x pl310 cache controller node. It uses fdt_fixup_table processed by ofw_fdt_fixup function. This fix-up is a part of device tree alignment between device trees from FreeBSD and Linux. arm,io-coherent property is used there, but due to a PL310 + UP bug it's added to the device tree in runtime. This issue was not a problem in FreeBSD, but in order to be on par with sys/gnu/dts/arm files, enable the fix-up.

This fix-up is a part of device tree alignment between device trees from FreeBSD and Linux. arm,io-coherent property is used there, but due to problems with coherent PL310 operation without CONFIG_SMP enabled, it's added to the device tree in runtime.
