Simon Glass 005174d661 x86: Allow I/O functions to use pointers ... It is common with memory-mapped I/O to use the address of a structure member to access memory, as in: struct some_regs { u32 ctrl; u32 data; } struct some_regs *regs = (struct some_regs *)BASE_ADDRESS; writel(1, &reg->ctrl); writel(2, &reg->data); This does not currently work with inl(), outl(), etc. Add a cast to permit this.
