The VBUSM2AXI bridge implements a leaky bucket mechanism at each LPT-HPT arbitration point. This will prevent LPT commands from getting stuck in the pipe forever due to overload of HPT commands.
A programmable system threshold will be used to trigger leaky bucket. This can be programmed in the EMIF_SSCFG_V2A_LEAKY_THRESH_REG. The threshold determines how many HPT commands can be sent in a row before a single LPT command is forwarded.
