Description
The doc shows how to add a memrange to a custom sbi domain by using dtb.
Is there some way to add a custom memrange to the sbi root domain while using dtb, which is only available by using sbi_domain_root_add_memrange in the code.

Research direction
Start with docs/domain_support.md and the existing sbi_domain_root_add_memrange path. Investigate how devicetree data is used for custom SBI domains and whether the root domain is handled separately. Done means establishing and documenting a supported devicetree mechanism, or clearly documenting why code remains required.
