Peng,
I see you've been able to get SPL DM_SERIAL to work on IMX8M. This
patch won't apply by the way due to commit ff1c7961d813 ("ARM: imx:
imx8mn-evk: enable DM_SERIAL") so I think you need to rebase.
I have not been able to get SPL DM_SERIAL to work on IMX8MM/IMX8MN...
it hangs my board. Is this due to moving preloader_console_init()
perhaps? Moving it didn't work for me.
Please explain the move of preloader_console_init() and please let me
know if you have tested this on imx/master. Fabio, perhaps you can
test?
Best Regards,
Tim

Peng,
I see my mistake now... the preloader_console_init() must come after
spl_early_init().
You still need to rebase on imx/master and you should also add a
comment to the commit such as:
"move the preloader_console_init() call after spl_early_init() to
avoid board hang" or perhaps you can come up with a reason for why the
board hangs otherwise. Is it that spl_early_init() does the relocation
and we need to be after that?
Best Regards,
Tim
