These changes are based on this vendor tree:
https://github.com/ADVANTECH-Corp/uboot-imx6.git
I adapted the files and compared them with code from similar imx8qm-mek board
Changes for v3:
- removed duplicate build_info
- removed CONFIG_FSL_ESDHC
Changes for v2:
- cleanup of u-boot environment
- set power mode SC_R_DC_0 for full boot of linux kernel
- enabled usdhc2
- enabled FEC defines
- updated README.md
- enabled readwrite for nfs rootfs
- removed include of environment header

+U-Boot for the NXP i.MX8QM ROM 7720a1 board
+
+Quick Start
+===========
+
+- Build the ARM Trusted firmware binary
+- Get scfw_tcm.bin and ahab-container.img
+- Get imx-mkimage
+- Build U-Boot
+- Build imx-mkimage
+- Flash the binary into the SD card
+- Boot
+
+Get and Build the ARM Trusted firmware
+======================================
+
+$ git clone https://source.codeaurora.org/external/imx/imx-atf
+$ cd imx-atf/
+$ git checkout origin/imx_4.14.78_1.0.0_ga -b imx_4.14.78_1.0.0_ga
+$ make PLAT=imx8qm bl31
+
+Get scfw_tcm.bin and ahab-container.img
+==============================
+
+$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-1.1.bin
+$ chmod +x imx-sc-firmware-1.1.bin
+$ ./imx-sc-firmware-1.1.bin
+$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.0.bin
+$ chmod +x firmware-imx-8.0.bin
+$ ./firmware-imx-8.0.bin
+
+Build U-Boot
+============
+
+$ export ATF_LOAD_ADDR=0x80000000
+$ export BL33_LOAD_ADDR=0x80020000
+$ make imx8qm_rom7720_a1_4G_defconfig
+$ make flash.bin
+$ dd if=u-boot.itb of=flash.bin bs=512 seek=854
+
+Get imx-mkimage
+==============================
+
+$ git clone https://source.codeaurora.org/external/imx/imx-mkimage/
+$ cd imx-mkimage
+$ git checkout rel_imx_4.14.78_1.0.0_ga -b rel_imx_4.14.78_1.0.0_ga
+$ cd iMX8QM/
+
+Copy the following binaries to iMX8QM folder:
+
+$ cp imx-atf/build/imx8qm/release/bl31.bin .
+$ cp u-boot/u-boot.bin .
+
+Copy the following firmwares U-Boot folder :
+
+$ cp firmware-imx-8.0/firmware/seco/mx8qm-ahab-container.img .
+$ cp imx-sc-firmware-1.1/mx8qm-val-scfw-tcm.bin scfw_tcm.bin
+
+$ make SOC=iMX8QM flash_linux_m4
+
+Flash the binary into the SD card
+=================================
+
+Burn the flash.bin binary to SD card offset 32KB:
+
+$ sudo dd if=flash.bin of=/dev/sd[x] bs=1k seek=32 conv=fsync
+
+Boot
+====
+Set Boot switch SW2: 1100.

yes vendor is advantech, I'll change that in next version
Then I need to move all files into the board/advantech folder?

yes indeed but this is the build target in the imx-mkimage repo. Which I
currently need to build the complete bootstream with ATF and scu.

Without this change the kernel is stucked during the boot. So currently
the kernel don't power up DC_0. So I would like to keep that until it is
fixed in the kernel.

should I use CONFIG_SYS_MALLOC_F_LEN=0x2000 ?

flash_linux_m4 is imx-mkimage target, not U-Boot target.
U-Boot already mkimage already has i.MX8QM support.

Enable CONFIG_DM_I2C and use dm_i2c_x api.

Drop CONFIG_OF_BOARD_SETUP if you not need it.

Sorry. 0x4000 is ok.

This should not be needed, I think. Did you enable DM_MMC?

Upstream u-boot has not added ahab feature, NXP downstream
support ahab.

I would like to avoid the imx-mkimage and use the internal mkimage support of
u-boot instead to create the complete bootstream.
but if I use:
$ make flash.bin
I run into this issue:
aarch64-linux-gnu-ld.bfd: invalid length for memory region .sram
scripts/Makefile.spl:404: recipe for target 'spl/u-boot-spl' failed
make[1]: *** [spl/u-boot-spl] Error 1
Makefile:1731: recipe for target 'spl/u-boot-spl' failed
make: *** [spl/u-boot-spl] Error 2
Some clue howto handle this?
Best Regards,
Oliver
