Hi Benjamin,
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@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
Success 0 Failure 0
7:3 1/ 1 [=================100%=================] SDP: boot -f build/mini/flash.bin
Please test this branch: https://github.com/lmajewski/u-boot/commits/phycore-imx8mm-qspi-nvme
On HOST: uuu -v -b qspi ~/work/DENX/u-boot/flash.bin
Stop on u-boot prompt.
u-boot=> fastboot 0
QSPI is flashed via USB - however - I've noticed that there are some flipped bits on USB transmission when I do compare it with tftp transfer.
This needs to be investigated, however seems to be an orthogonal problem from QSPI boot support.
Log on target:

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

After this change it would be possible to boot SDP gadget when Phytec's Phycore imx8mm module has USB ROM boot selected.
With this change it shall be possible to flash eMMC/SD card content with uuu program.
