Our internal 85xx system test boards (CTS) have a mux for the local-bus controller chip-select 0 to enable switching between 8-bit and 16-bit NAND devices. > It seems to be no real problem to me when you have to > reconfigure U-Boot and build another image when switching to > another piece of hardware that is incompatible enough to use > different bus widths. Yeh, that is what I do now, but it would be nice to have a single image. -EdS _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
