Split this up into two separate functions (validation/setting boot params in one, scanning in another) to allow for additional setup between boot params and scanning the memory.

* of/fdt: Convert FDT functions to use libfdtRob Herring2014-04-301-1/+0
| | | | | | | | | | | | | | | | | | | The kernel FDT functions predate libfdt and are much more limited in functionality. Also, the kernel functions and libfdt functions are not compatible with each other because they have different definitions of node offsets. To avoid this incompatibility and in preparation to add more FDT parsing functions which will need libfdt, let's first convert the existing code to use libfdt. The FDT unflattening, top-level FDT scanning, and property retrieval functions are converted to use libfdt. The scanning code should be re-worked to be more efficient and understandable by using libfdt to find nodes directly by path or compatible strings.

* drivers: of: add initialization code for static reserved memoryMarek Szyprowski2014-03-111-0/+4
| | | | | | | | | | | | | | | | | | | 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_infoKevin Hao2014-01-091-0/+1
| | | | | | | | | | | | | 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).

| * of: Specify initrd location using 64-bitSantosh Shilimkar2013-07-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some PAE architectures, the entire range of physical memory could reside outside the 32-bit limit. These systems need the ability to specify the initrd location using 64-bit numbers. This patch globally modifies the early_init_dt_setup_initrd_arch() function to use 64-bit numbers instead of the current unsigned long. There has been quite a bit of debate about whether to use u64 or phys_addr_t. It was concluded to stick to u64 to be consistent with rest of the device tree code. As summarized by Geert, "The address to load the initrd is decided by the bootloader/user and set at that point later in time. The dtb should not be tied to the kernel you are booting" More details on the discussion can be found here: https://lkml.org/lkml/2013/6/20/690 https://lkml.org/lkml/2012/9/13/544 Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Vineet Gupta <vgupta@synopsys.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Grant Likely <grant.likely@linaro.org>
