bridge_ddrreg_sprt_8_118_p_2 

         This register describes the weight value of each QoS supported at the bridge. Each byte of this register must be greater than or equal to 3. Each transmitting bridge supports up to 16 QoS profiles. Each QoS is composed of priority and weight, however only the weight is programmable, therefore is part of the registers.
QoS data is composed of four registers, P0, P1, P2, and P3, each of which contains the weight of four profiles. Depending upon how many QoS profiles are enabled, the appropriate bits in the following registers are available.

Size: 32

Offset: 0x8010

Access: RW

Access mode: SECURE | PRIVILEGEMODE

Note: The processor must make a secure, privileged bus access to this register. You can configure processor mode settings in the control registers of the ARM Cortex-A53 MPcore processor. For more information about processor modes, please refer to the ARM Infocenter.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
