+U-Boot for the Toradex Verdin iMX8M Mini Module
+
+Quick Start
+===========
+
+- Build the ARM trusted firmware binary
+- Get the DDR firmware
+- Build U-Boot
+- Flash to eMMC
+- Boot
+
+Get and Build the ARM Trusted Firmware (Trusted Firmware A)
+===========================================================
+
+$ echo "Downloading and building TF-A..."
+$ git clone -b imx_4.14.98_2.3.0 https://source.codeaurora.org/external/imx/imx-atf
+$ cd imx-atf
+
+Please edit `plat/imx/imx8mm/include/platform_def.h` so it contains proper
+values for UART configuration and BL31 base address (correct values listed
+below):
+#define BL31_BASE		0x910000
+#define IMX_BOOT_UART_BASE	0x30860000
+#define DEBUG_CONSOLE		1
+
+Then build ATF (TF-A):
+$ make PLAT=imx8mm bl31
+
+Get the DDR Firmware
+====================
+
+$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.4.1.bin
+$ chmod +x firmware-imx-8.4.1.bin
+$ ./firmware-imx-8.4.1.bin
+$ cp firmware-imx-8.4.1/firmware/ddr/synopsys/lpddr4*.bin ./
+
+Build U-Boot
+============
+
+$ export CROSS_COMPILE=aarch64-linux-gnu-
+$ make verdin-imx8mm_defconfig
+$ make flash.bin
+
+Flash to eMMC
+=============
+
+> tftpboot ${loadaddr} flash.bin
+> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
+> mmc dev 0 1 && mmc write ${loadaddr} 0x2 ${blkcnt}
+
+As a convenience, instead of the last two commands one may also use the update
+U-Boot wrapper:
+> run update_uboot
+
+Boot
+====
+
+ATF, U-boot proper and u-boot.dtb images are packed into FIT image,
+which is loaded and parsed by SPL.
+
+Boot sequence is:
+SPL ---> ATF (TF-A) ---> U-boot proper
+
