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. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
