Marek Szyprowski Nov. 7, 2018, 3:05 p.m.
This patch adds support for Exynos5433 based TM2 and TM2e boards.

u-boot is used to load and decompress kernel image or alternatively
(when 'volume down' button is pressed during boot) provide THOR download
USB feature for flashing kernel and rootfs images.

Based on earlier work done by Lukasz Majewski <l.majewski@samsung.com>.
