I think changes should be tested prior merged them into upstream.
Untested patches can cause other hidden issues.

Also as I wrote, other SD patches for EspressoBin copied+pasted from
Marvell's did not worked as is applied on current upstream U-Boot. And
also argument that "patch is similar as other node" is not reason to not
test changed. As a first thing which I did for SD card support on
EspressoBin was that I copied DTS node from Turris MOX... and on
EspressoBin it did not worked. On MOX was card working fine.
