[PATCH] configs: xilinx: Enable configs required for ubifs

[Michal Simek]

From: Ashok Reddy Soma <ashok.reddy.soma at xilinx.com>

Enable required configs for using ubifs in uboot.

UBIFS testing procedure from u-boot:
Let's say we have two partitions in dt as below and want to format
partition1 "images" with ubifs.

	partition at 0 {
		label = "boot";
		reg = <0x0 0x1000000>;
	};

	partition at 1 {
		label = "images";
		reg = <0x1000000 0x7000000>;
	};

We will format the partition from linux and copy some files and access
from uboot later.
First thing, in linux config disable CONFIG_MTD_SPI_NOR_USE_4K_SECTORS.
this is required as ubifs expects min LEB size as 15*1024 bytes.

Use below commands in linux to format "images" partition with ubifs.

ubiformat /dev/mtd1
ubiattach /dev/ubi_ctrl -m 1
ubimkvol /dev/ubi0 -N images -m
mount -t ubifs ubi0:images /mnt

We can copy files to /mnt and unmount it.

To access this ubifs partition from uboot, run below commands.
(Don't forget to probe device before, e.g. sf probe 0 0 0)

setenv mtdids "nor0=nor0"
setenv mtdparts "mtdparts=nor0:16m(boot),112m(images)"
ubi part images
ubifsmount ubi0:images

make sure we match "mtdparts" to whatever is given in dt w.r.t partition
sizes.

"mtdparts" command will list the mtd partitions in u-boot.

Once ubifs is mounted, we can use "ubifsls" to list the files in that
partition and use "ubifsload <addr> <filename>" to load files from ubifs
partition to DDR.

Reading information about mtd layout from DT is not supported.
