Add support for Qualcomm QCS404 SoC based evaluation board.
Features:
- Qualcomm Snapdragon QCS404 SoC
- 1GiB RAM
- 8GiB eMMC, uSD slot
U-boot is chain loaded by ABL in 64-bit mode as part of boot.img.
For detailed build and boot instructions, refer to

+QCS404 EVB
+==========
+
+About this
+----------
+This document describes the information about Qualcomm QCS404 evaluation board
+and it's usage steps.
+
+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
+------------
+Build
+^^^^^
+Setup ``CROSS_COMPILE`` for aarch64 and build U-Boot for your board::
+
+ $ export CROSS_COMPILE=<aarch64 toolchain prefix>
+ $ make qcs404evb_defconfig
+ $ make
+
+This will build ``u-boot.bin`` in the configured output directory.
+
+Generate FIT image
+^^^^^^^^^^^^^^^^^^
+A ``qcs404.its`` file can be found in ``board/qualcomm/qcs404-evb/`` directory.
+It expects a folder as ``qcs404_imgs/`` in the main directory containing
+pre-built kernel, dts and ramdisk images. See ``qcs404.its`` for full path to
+images.
+
+- Build FIT image::
+
+ mkimage -f qcs404-evb.its qcs404-evb.itb
+
+Pack android boot image
+^^^^^^^^^^^^^^^^^^^^^^^
+We'll assemble android boot image with ``u-boot.bin`` instead of linux kernel,
+and FIT image instead of ``initramfs``. Android bootloader expect gzipped kernel
+with appended dtb, so let's mimic linux to satisfy stock bootloader:
+
+- create dump dtb::
+
+ workdir=/tmp/prepare_payload
+ mkdir -p "$workdir"
+ cd "$workdir"
+ mock_dtb="$workdir"/payload_mock.dtb
+
+ dtc -I dts -O dtb -o "$mock_dtb" << EOF
+ /dts-v1/;
+ / {
+ model = "Qualcomm Technologies, Inc. QCS404 EVB 4000";
+ compatible = "qcom,qcs404-evb-4000", "qcom,qcs404-evb", "qcom,qcs404";
+
+ #address-cells = <2>;
+ #size-cells = <2>;
+
+ memory@80000000 {
+ device_type = "memory";
+ /* We expect the bootloader to fill in the size */
+ reg = <0 0x80000000 0 0>;
+ };
+
+ chosen { };
+ };
+ EOF
+
+- gzip u-boot ``gzip u-boot.bin``
+- append dtb to gzipped u-boot: ``cat u-boot.bin.gz "$mock_dtb" > u-boot.bin.gz-dtb``
+
+Now we've got everything to build android boot image:::
+
+ mkbootimg --kernel u-boot.bin.gz-dtb \
+ --ramdisk qcs404-evb.itb --pagesize 4096 \
+ --base 0x80000000 --output boot.img
+
+Flash image on qcs404-evb using fastboot method.
