Due to the flash layout (the 4 first sectors size is 32KB) using
"flash write_image erase" command, as you did, can't be used anymore due
to the SPL size increase.
SPL size is over 32KB (0x8000), so SPL binary occupies the first and a part
of the second 32KB sectors.
When you execute "flash write_image erase u-boot-dtb.bin 0x08009000",
this command erase the second 32KB sector (where a part of SPL has been
previously copied) before copying the u-boot-dtb.bin binary.
So i advice you to use the method described in doc/board/st/stm32_MCU.rst
Copy directly the generated binary u-boot-with-spl.bin into the mass-storage
exposed by the board.
Example, under Ubuntu you should see the following directory
/media/$USER/DIS_F746NG

Yes, i have tested the kernel v6.0-rc4 on STM32F746-disco board recently.
Before you have to apply the attached patch.
