Commit Message

Marek Szyprowski Nov. 7, 2018, 3:04 p.m. UTC
This patch adds minimal support for Exynos5433 SoC (ARM64 based).

The following devices are supported:
- mmc0 (for eMMC)
- serial1 (for debug/console)
- gpa0..3 and gpb0..2 GPIO banks

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

The config_writelist.txt is to prevent from adding new CONFIG_* options
to include/configs/<myboard>.h

The CONFIG_EXYNOS5433 shall be added to a proper Kconfig
