Re: [pci] PCI target

[liei@vlsi.zju.edu.cn]

         I cannot figure out that which kind of memory do you prefer to 
build up the "configuration space" , EEPROM or SRAM , or either is ok ? 
And what is the advantage of EEPROM and SRAM to build up for 
the "configuration space" ?  Can you help me to get a clear view of this 
point ? Thank you very much , and sorry for interruping :)
