Can't you have a control register that does an indirect read/write, but maintain an internal pointer in the hardware? that way you could do writel(control, address) writel(datareg, data1) writel(datareg, data2) writel(datareg, data3) etc. Same would go for reading (since you only maintain a single pointer anyway). Not sure if that's feasible though. johannes
