Hello Romain,
The following features were removed to reduce the memory footprint of the

The code seems to handle 3 endpoints ?
Yes, I'm talking in terms of USB endpoint numbers here, so endpoints 0-2 are
handled.

But why not handle the additional endpoints ?
Because I didn't see a major use case for them in U-Boot, and removing their
handling allowed a reduction in code and program volume which seems relevant
for U-Boot.
Also, can you test whether 'ums 0 mmc 0.1,0.2,0' works to expose eMMC HW
BOOT partitions and HW USER partition as three separate UMS devices over
the same USB connection ?
Sure, I'll give it a try.
Thank you !
