This patchset fixes GPIO information of Exynos5420 which is needed to
support Exynos5422 Odroid XU3 board. On the base of the fixes, this
patchset adds support for Exynos5422 Odroid XU3 board. I have done this
work on the master branch in http://git.denx.de/u-boot-samsung.git (sha1:
26f195c71252e98aebfffd5cfa994a4475559370) with patches by Akshay Saraswat.

link: https://patchwork.ozlabs.org/patch/405246/ (updated)

How to test this patch:
1. git clone http://git.denx.de/u-boot-samsung.git
2. git reset --hard 26f195c71252e98aebfffd5cfa994a4475559370
3. Get and apply the patchset of Akshay Saraswat

	https://patchwork.ozlabs.org/patch/405251/
	https://patchwork.ozlabs.org/patch/405252/
4. Apply this patchset
5. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- odroid-xu3_config
6. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j8
7. Now you can use u-boot-dtb.bin for your downloading

Note: If you use micro SD card for your test you have to apply the below
patch additionally. This patch is needed, because micro sd card is
recognized as MMC1 instead of MMC0. Additional work is needed to make it
work regardless of device id.
