Hi Fabio,
I share here a more recent version of your series:

https://patchwork.amarulasolutions.com/project/linux-amarula/list/?series=371

This series brings USB gadget support for i.MX8MM
and allows the usage of the Serial Download Protocol,
which is a convenient way for loading U-Boot via the
'uuu' tool and and flashing the eMMC via the U-Boot
'ums' command.

Tested on board based on iMX8MM SOC:
