[U-Boot] [PATCH v5 3/3] ARMV7: Exynos4: Add support for TRATS board

[HeungJun, Kim <riverful.kim@samsung.com>]

This patch adds support for Samsung TRATS board

Signed-off-by: HeungJun, Kim <riverful.kim@samsung.com>
Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
---
Changes for v2:
   - sort the list of the name in MAINTAINERS
   - modify to GPLv2+
   - change assem code in lowlevel_init.S to C code in lowlevel_util.c
   - do not defile values for variables if the variable is feature
   - remove miscellaneouses

Changes for v3:
   - implement lowlevel_init.S by C
   - remove lowlevel_init.S, the functions is inserted into trats.c
   - add watchdog.h for Exynos4
   - add power.h amd modify cpu.h for Exynos4

Changes for RESEND since v3
   - Add prefix board_ for board functions
   - Rename setup.h from trats_setup.h
   - Remove *_OFFSET in setup.h
   - Remove GPIO and UART definitions in setup.h

Changes for v4:
   - add selection UART direction for TRATS board

Changes for v5:
   - replace lowlevel_init() to board_early_init_f().
   - add CONFIG_SKIP_LOWLEVEL_INIT, CONFIG_BOARD_EARLY_INIT_F
