There is no patch that needs to be applied for PLB arbiter configuration.

Yuri's configuration from RAID driver should be droppred coz changing MQ/PLB4 registers from Linux is not recommended

Yuri's patch does the following - set RLPM (read passing limit) bits in MQ register to 1, - set WRCL (MCIF cycle limit) in MQ registers to 1. In my testing, as far as I can remember, these values were set to 1 by default. I had tested with Canyonlands, Kilauea, Katmai and Glacier boards. So unless Yuri found that these values were not default values in some processor, Yuri's patch should be applied. Thanks, Prodyut
