Hi Tommaso,

are you willing to share a parch that applies cleanly to 2022.07-rc2, I 
tried to collect all the patches spread on the mailing list since the 
end of 2020, but it seems that I'm missing some, because I still get 
references to non-exiting functions and such .

iMX8MM is now a "hot" MCU, that had the SPL SDP functionality working 
perfectly with the NXP tree, I still don't understand why a (maybe) not 
elegant implementation was removed without being replaced with, well, 
anything, and in the process the activation of DM_xxx and DM_SPL_xxx 
made a mess of everything and producing a series of misleading 
compilation errors.

Kindly please post the patch here if possible, so the poor souls that 
still need SPL SDP functionality for iMX8MM to be able to use it.


  Many thanks and regards,

Mircea
