From e8d9d1f5485b52ec3c4d7af839e6914438f6c285 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 28 Feb 2014 14:42:47 +0100 Subject: [PATCH] drivers: of: add initialization code for static reserved memory This patch adds support for static (defined by 'reg' property) reserved memory regions declared in device tree. Memory blocks can be reliably reserved only during early boot. This must happen before the whole memory management subsystem is initialized, because we need to ensure that the given contiguous blocks are not yet allocated by kernel. Also it must happen before kernel mappings for the whole low memory are created, to ensure that there will be no mappings (for reserved blocks). Typically, all this happens before device tree structures are unflattened, so we need to get reserved memory layout directly from fdt.
