The MPAMF_PARTID_NRW_IDR characteristics are:
Indicates the largest internal PARTID for this MSC.
MPAMF_PARTID_NRW_IDR_s indicates the largest Secure internal PARTID. MPAMF_PARTID_NRW_IDR_ns indicates the largest Non-secure internal PARTID.
When FEAT_RME is implemented: MPAMF_PARTID_NRW_rt indicates the largest Root internal PARTID. MPAMF_PARTID_NRW_rl indicates the largest Realm internal PARTID.
PARTID narrowing is global to the MSC and does not vary by resource instance.
The power domain of MPAMF_PARTID_NRW_IDR is IMPLEMENTATION DEFINED.
This register is present only when FEAT_MPAM is implemented and MPAMF_IDR.HAS_PARTID_NRW == 1. Otherwise, direct accesses to MPAMF_PARTID_NRW_IDR are RES0.
The power and reset domain of each MSC component is specific to that component.
MPAMF_PARTID_NRW_IDR is a 32-bit register.

RES0 | INTPARTID_MAX |
Reserved, RES0.
The largest intPARTID supported in this MSC.
This register is within the MPAM feature page memory frames. In a system that supports Secure, Non-secure, Root, and Realm memory maps, there must be MPAM feature pages in all four address maps.
MPAMF_PARTID_NRW_IDR is read-only.
MPAMF_PARTID_NRW_IDR must be readable from the Non-secure, Secure, Root, and Realm MPAM feature pages.
MPAMF_PARTID_NRW_IDR is permitted to have the same contents when read from the Secure, Non-secure, Root, and Realm MPAM feature pages unless the register contents are different for the different versions:
There must be separate registers in the Secure (MPAMF_PARTID_NRW_IDR_s), Non-secure (MPAMF_PARTID_NRW_IDR_ns), Root (MPAMF_PARTID_NRW_IDR_rt), and Realm (MPAMF_PARTID_NRW_IDR_rl) MPAM feature pages.
