Hi  My platform os linux  work on IMX6, FPGA via switch connect to IMX RC,I use linux tools of lspci/setpci to access switch regs,  but when addresses more then 0x1000,something wrong, lspci/setpci can't work,  anybody help me

switch regs initial by EEROM,but I  can't burn EEROM everytime, so I need strong tools like lspci to  access more then 0x1000 address;  Sincere thanks
