The ePAPR specification says that phandle properties should be called "phandle", and not "linux,phandle". To facilitate the migration from "linux,phandle" to "phandle", introduce function fdt_create_phandle(), which creates a phandle in a given node. For now, we create both the "phandle" and "linux,phandle" properties. A later version of this function will remove support for "linux,phandle". Signed-off-by: Timur Tabi <timur@freescale.com>
Introduce two functions, fdt_verify_alias_address() and fdt_get_base_address(), which can be used to verify the physical address of a device in a device tree. fdt_get_base_address() returns the base address of an SOC or PCI node. fdt_verify_alias_address() prints a message if the address of a node specified by an alias does not match the given physical address.

The initrd_end variable contains the address immediately *after* the initrd blob, not the last address containing data. This patch fixes an inadvertent off-by-one when setting up the initrd reserved map. Signed-off-by: Grant Likely <grant.likely@linaro.org>
When fdt_fixup_memory_banks is called with 2-cell address and size fields in the device-tree (IE: 64-bit address and size), then it will overflow its on-stack "tmp" buffer. This fixes the buffer size and adds a comment explaining how many bytes need to be allocated per record.

Commit a6bd9e8 "FDT: Add fixup support for multiple banks of memory" removed code but forgot to remove the variables used by it, resulting in warnings: fdt_support.c: In function 'fdt_fixup_memory_banks': fdt_support.c:399: warning: unused variable 'sizecell' fdt_support.c:399: warning: unused variable 'addrcell' Remove the declarations, too.

Boards can pass display timing info for drivers using EDID block. Provide common function to add board specific EDID data to the device tree. Subsequent patch makes use of this functionality. Detailed timing descriptor data from EDID is used for programming the display controller. This is currently implemented on the Linux side by the fsl-diu-fb frame buffer driver and it is documented there in Documentation/powerpc/dts-bindings/fsl/diu.txt.

This patch fixes a bug in fdt_fixup_nor_flash_node() when the reg property has multiple reg tuples, like: reg = <0 0x00000000 0x04000000 0 0x04000000 0x04000000>; In this case this function did not update the reg property correctly. Signed-off-by: Stefan Roese <sr@denx.de>
