+U-Boot for the NXP i.MX8QXP EVK board
+
+Quick Start
+===========
+
+- Build U-Boot
+- Build the ARM Trusted firmware binary
+- Get scfw_tcm.bin and ahab-container.img
+- Get mkimage tool
+- Generate flash.bin using imx-mkimage
+- Flash the binary into the SD card
+- Boot
+
+Build U-Boot
+============
+
+$ make imx8qxp_mek_defconfig

+$ cp u-boot/u-boot-nodtb.bin imx-mkimage/iMX8M/

+
+If you want to run with HDMI, copy signed_hdmi_imx8m.bin to imx-mkimage/iMX8M.
+
+Before generating the flash.bin, transfer the mkimage generated by U-Boot to iMX8M folder:
+
+$ cp u-boot/tools/mkimage imx-mkimage/iMX8M/
+$ mv imx-mkimage/iMX8M/mkimage imx-mkimage/iMX8M/mkimage_uboot
+
+$ cd imx-mkimage/
+$ make SOC=iMX8M flash_spl_uboot
+
+Or for using HDMI:
+
+$ make SOC=iMX8M flash_hdmi_spl_uboot
+
+Flash the binary into the SD card
+=================================
+
+Burn the flash.bin binary to SD card offset 33KB:
+
+$ sudo dd if=iMX8M/flash.bin of=/dev/sd[x] bs=1024 seek=33
+
+Boot
+====
+Set Boot switch SW801: 1100 and Bmode: 10 to boot from Micro SD.
