+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
+$ make
+
+Get and Build the ARM Trusted firmware
+======================================
+
+$ git clone https://source.codeaurora.org/external/imx/imx-atf
+$ cd imx-atf/
+$ git checkout origin/imx_4.9.88_imx8qxp_beta2 -b imx_4.9.88_imx8qxp_beta2
+$ make PLAT=imx8qxp bl31
+
+Get scfw_tcm.bin and ahab-container.img
+==============================
+
+$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-0.7.bin
+$ chmod +x imx-sc-firmware-0.7.bin
+$ ./imx-sc-firmware-0.7.bin
+$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-7.6.bin
+$ chmod +x firmware-imx-7.6.bin
+$ ./firmware-imx-7.6.bin
+
+Get imx-mkimage tool
+==============================
+Download the imx-mkimage tool:
+
+$ git clone https://source.codeaurora.org/external/imx/imx-mkimage/
+$ cd imx-mkimage/
+$ git checkout origin/imx_4.9.88_imx8qxp_beta2 -b imx_4.9.88_imx8qxp_beta2
+
+
+Generate flash.bin using imx-mkimage
+====================================
+
+Copy the following binaries to imx-mkimage/iMX8M folder:
+
+$ cp imx-atf/build/imx8qxp/release/bl31.bin imx-mkimage/iMX8QX/
+$ cp u-boot/u-boot.bin imx-mkimage/iMX8QX/
+
+Copy the following firmwares to imx-mkimage/iMX8 folder :
+
+$ cp firmware-imx-7.6/firmware/seco/ahab-container.img imx-mkimage/iMX8QX/
+$ cp imx-sc-firmware-0.7/mx8qx-mek-scfw-tcm.bin imx-mkimage/iMX8QX/scfw_tcm.bin
+
+$ cd imx-mkimage/
+$ make SOC=iMX8QX flash
+
+Flash the binary into the SD card
+=================================
+
+Burn the flash.bin binary to SD card offset 32KB:
+
+$ sudo dd if=iMX8QX/flash.bin of=/dev/sd[x] bs=1024 seek=32
+
+Boot
+====
+Set Boot switch SW2: 1100.

+U-Boot for the NXP i.MX8MQ EVK board
+
+Quick Start
+===========
+
+- Build U-Boot
+- Build the ARM Trusted firmware binary
+- Get DDR firmware and mkimage tool
+- Generate flash.bin using imx-mkimage
+- Flash the binary into the SD card
+- Boot
+
+Build U-Boot
+============
+
+$ make mx8mq_evk_defconfig
+$ make
+
+Get and Build the ARM Trusted firmware
+======================================
+
+$ git clone https://source.codeaurora.org/external/imx/imx-atf
+$ cd imx-atf/
+$ git checkout origin/imx_4.9.51_imx8m_beta
+$ make PLAT=imx8mq bl31
+
+Get the DDR firmware and mkimage tool
+==============================
+
+$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-7.2.bin
+$ chmod +x firmware-imx-7.2.bin
+$ ./firmware-imx-7.2.bin
+
+Download the imx-mkimage tool:
+
+$ git clone https://source.codeaurora.org/external/imx/imx-mkimage/
+$ cd imx-mkimage/
+$ git checkout origin/imx_4.9.51_imx8m_beta
+
+
+Generate flash.bin using imx-mkimage
+====================================
+
+Copy the following binaries to imx-mkimage/iMX8M folder:
+
+$ cp imx-atf/build/imx8mq/release/bl31.bin imx-mkimage/iMX8M/
+$ cp u-boot/u-boot-nodtb.bin imx-mkimage/iMX8M/
+$ cp u-boot/spl/u-boot-spl.bin imx-mkimage/iMX8M/
+$ cp u-boot/arch/arm/dts/fsl-imx8mq-evk.dtb imx-mkimage/iMX8M/
+
+Copy the following firmwares to imx-mkimage/iMX8 folder :
+
+$ cp firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem.bin 
imx-mkimage/iMX8M/
+$ cp firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem.bin 
imx-mkimage/iMX8M/
+$ cp firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem.bin 
imx-mkimage/iMX8M/
+$ cp firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem.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.
