Subject: powerpc/BSC9132QDS: Enable creation of dynamic partition for NAND and NOR
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=42a9e2fe1be0f8879ad0928e05116e5a4c7cea1a;p=u-boot.git

powerpc/BSC9132QDS: Enable creation of dynamic partition for NAND and NOR

* fdt_fixup_mtdparts is called from ft_board_setup
 * run "mtdparts default" to create NAND, NOR partition on uboot
 * Use mtdparts to create partitions dynamically rather
    than using static partitions in device tree
