-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
-

-U-Boot SPL 2020.01-00187-gd411d164e5 (Jan 26 2020 - 04:47:26 +0100)
