In my last changeset for relocation I found some implementation in a/a/c/pxa/start.S which do save the register to stack before copy_loop, use almost all registers (only r8 is not used which is gd_t for arm, but I think it could be used here too cause it is saved on the stack) and save the registers back later on. I guess this could fasten the copy_loop a bit but needs to be proven. Anthony, if you change all start.S could you consider this also? best regards Andreas Bießmann _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
