The code is not all that complex. Most of the code is the same, there is just a thin HAL over it. And it is _NOT_ for reading two SPDs on different busses, it is for consistency and uniformity. Reading two SPDs is a free bonus, there is no a single line of additional code for this. --- ****************************************************************** * k...@home KOI8 Net < > The impossible we do immediately. * * Las Vegas NV, USA < > Miracles require 24-hour notice. * ****************************************************************** _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
