QMAN_BAR{E} register setup was disabled on ARM platforms, however the
register does need to be set. Enable the code also on ARMs and fix the
CONFIG_SYS_QMAN_MEM_PHYS define to the correct value so that the newly
enabled code works.

Here goes my understanding:
RTIC are independent device from JR and QI, So they should be assigned different unique steam-id. Also each RTIC are independent device, so each RTIC can also be assigned separate stream-id.
While we can decide to use one stream-id for all RITCs and add a comment that they are not partitionable.
DECOs can take work from QI or JRs, and in that case they will use the stream-id of the respective QI or JR, and the stream-id programmed in DECOs is not used.
While DECOs can be used directly (not via JR and QI) and in that case it will use the strema-id programmed in it. So in this case also we should be using unique stream-id for each DECO if partitionable or one for all DECOs

Considering the HW offers the mechanism to program the ICIDs (and assuming the
HW is correctly designed), it follows that these HW blocks could be used
independently.
The only way to implement a *mechanism* is to provide different ICIDs for all
the blocks.
Any other solution would be imposing a *policy*, thus restricting user's
possibilities. Admittedly there are use cases less "popular" than others, but if
possible it would be best not to decide for the user and provide full flexibility.
Is there a resource (ICID values) shortage?
Thanks,

No. I can change the patch to have distinct ICIDs and resubmit. Please
let me know if you agree on this.

Yes, this is my suggestion.
IIUC it's also similar to the way LIODNs are allocated on PPC.
True, LS102x is the exception - it assigns ICID 0x10 to all SEC blocks.

Yes, please assign separate ICIDs for each.
