Samsung S9 SM-G9600 - Snapdragon SDM845 version of the phone,
for China \ Hong Kong markets.
Has unlockable bootloader, unlike SM-G960U (American market version),
which allows running u-boot as a chain-loaded bootloader.

+Snapdragon 845
+================
+
+About this
+----------
+This document describes the information about Qualcomm Snapdragon 845
+supported boards and it's usage steps.
+
+SDM845 - hi-end qualcomm chip, introduced in late 2017.
+Mostly used in flagship phones and tablets of 2018.
+
+U-Boot can be used as a replacement for Qualcomm's original ABL (UEFI) bootloader.
+It is loaded as an Android boot image through ABL
+
+Installation
+------------
+First, setup ``CROSS_COMPILE`` for aarch64. Then, build U-Boot for your board::
+
+ $ export CROSS_COMPILE=<aarch64 toolchain prefix>
+ $ make <your board name here, see Boards section>_defconfig
+ $ make
+
+This will build ``u-boot.bin`` in the configured output directory.
+
+Boards

+^^^^^^^^^^^^
+
+The starqltechn is a production board for Samsung S9 (SM-G9600) phone,
+based on the Qualcomm SDM845 SoC.
