Hi Lukasz,
did you test this? It does not work for me. When I try it, the U-Boot
hangs in SPL. Here is what I got:
From Host:
bhahn at llp-hahn:~/git-repos/u-boot$ sudo uuu -b spl build/mini/flash.bin
uuu (Universal Update Utility) for nxp imx chips -- lib1.4.193

To me it looks like there are some changes missing to get this feature
to work.
You can take a look at my commits where I added this feature for imx8mp.
199229e28b2b2da57c52ee46452f930785cf6002 ("phycore-imx8mp: add USB mass
storage support")
8dcf1df48dff339b172d1bce2a38a965ee4aafca ("phycore-imx8mp: add support
for booting and flashing emmc via UUU")
Here are the changes I needed to do on top of your patch to get this
feature to work for mini:

With these changes booting via SDP with uuu and flashing emmc with uuu
should work. Sadly I did not find a way to be able to flash eMMC and
SD-Card over uuu with the same bootloader because it was necessary for
me to specify the device to flash in CONFIG_FASTBOOT_FLASH_MMC_DEV.
with kind regards,
Benjamin
