use 2 mesa 5i25

is it posible to use 2 mesa 5i25 in a PC? i cant firgure out how to flash firmware for this and how hal components work.

Sure, there is no firmware difference, with two cards, the hal pins will appear as
hm2_5i25.0.xxxxxxx and
hm2_5i25.1.xxxxxxx

but i dont know how to flash 2 difference firmwares for 2 mesa cards. I dont see any argument to difference 1nd and 2rd card In the command:
sudo mesaflash --device 5i25 write xxx.bit

I dont think mesaflash can do this, just flash one at a time
