==GP1 commands handling==
PS1DRV 1.1.0 handle GP1 (0x00,0x01,0x03,0x05-0x08) on software side, while commands 0x02, 0x04, and 0x10 are completely ignored by PS1DRV. This imply some kind of hardware behavior on PGIF side that take care of mentioned CMDs.
GP1 parser function is at 0x201D1C, a0 is command from buffer (0x70000060) which is previously read from sfifo.<br>
Function which read GP1 from sfifo is located at 0x204F08, and is set as pgif handler using syscall 114. Function additionally check if command is 0/1, if yes then flag indicating gp0 fifo flush in near future is set. This shorten time where pgif wait for gfifo, and eventually give up since flush is in the plan anyway.
