I seem to understand that remapping, being a CPU specific and depending on a way U-Boot starts (either from ROM or RAM), is taken away in 'lowlevel_init' function, defined either in in $(uboot)/cpu/arm/$(soc)/lowlevel_init.S (for example, $(uboot)/cpu/arm920t/ks8695/) or in $(uboot)/board/board_name/lowlevel_init.S, but what confuses me is that I couldn't find remap functions on every ARM platform, running from ROM at reset. -- Roman Mashak _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
