Subject: mtd: nand: mxs_nand: move structs into header file
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=68748340c8613877d71b444c0dffe63b536d5a5f;p=u-boot.git

mtd: nand: mxs_nand: move structs into header file

Move structs into header file so we can use a separate compile
unit for device tree support.
