driver: how to do adressing..(register or byte)
hello
I'm new to linux driver programming and even to linux programming..i've made a driver for a PCI card and all goes ok but the hardware disigner wants me to modify the driver so he can address his memory space on four bytes (a register). now he has an adress for each byte ..and he wants to have an adress for each four bytes
he told me that there's a signal on PCI bus C/BE [3..0] and the driver must reset C/BE[3] to obtain a register adressing..
have anybody any idia how to do this?
sorry for my english ..and thanks to all
bye
