readl() and other I/O accessors take pointers, not integer addresses.
Hi Scott
I fixed the others error, only this one I don't know how to do that. can you point me to some example.
You need a pointer of appropriate type (u32, in this case) that points to the address. Usually this is done with a struct that describes the register layout (e.g. struct nfc_regs in drivers/mtd/nand/mxc_nand.c).
The alternative is to cast the address to a pointer before passing it to the accessor, though Wolfgang doesn't like this.
