Hi Peng,
I'm working with an IMX8MM with U-Boot master + your v3 i.MX8MM-support series. I have a few comments and questions below.

Build fails due to default_serial_console undefined. Did you need to enable DM_SERIAL?
After enabling DM_SERIAL build fails during image creation:
MKIMAGE u-boot.itb ./tools/imx8m_image.sh spl/u-boot-spl.cfgout 1 26061+0 records in 26061+0 records out 104244 bytes (104 kB, 102 KiB) copied, 0.0458568 s, 2.3 MB/s MKIMAGE flash.bin Not support no fit arch/arm/mach-imx/Makefile:151: recipe for target 'flash.bin' failed
If I hack using_fit=1 into tools/imx8mimage.c I can build flash.bin but it does not boot.
Am I missing some additional necessary patches to tools?
Best Regards,
Tim
