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.

If we introduce a dt property to describe memory as hotpluggable, configs supporting early fdt may then also do this marking and use movable nodes.

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.

powerpc: introduce early_get_first_memblock_info For a relocatable kernel since it can be loaded at any place, there is no any relation between the kernel start addr and the memstart_addr. So we can't calculate the memstart_addr from kernel start addr. And also we can't wait to do the relocation after we get the real memstart_addr from device tree because it is so late. So introduce a new function we can use to get the first memblock address and size in a very early stage (before machine_init).
