[U-Boot] [PATCH v2 0/3] Support eMMC reset using DT for some exynos boards

[Joonyoung Shim]

This patchset is to support eMMC reset using DT for some exynos boards
e.g. Odroid X2/U3/XU3.

It needs to reset eMMC memory to perform complete reboot, so we should
handle nRESET_OUT line specially. nRESET_OUT line is connected to gpio
and it can have different gpio by boards, so we will get gpio from DT.

This patchset is based on http://git.denx.de/u-boot-dm.git gpio-working
branch.

Thanks.

Changes from v1:
- s/SD4_nRESET_OUT/nRESET_OUT
- Remove codes for non DT case
- Add comments about eMMC reset delay time
