The __got_start misalignment makes num_got_entries larger than needed. As a result, we update GOT entries too many and corrupt top of the u_boot_cmd data. This will be fixed by __got_{start,end} cleanups in linker scripts. In addition to fixing above, I've takan $gp usage fix suggested by Vlad, and cleaned up linker scripts, etc. Please review and give it a try. thanks, Shinya
