mpc8641 image size cleanup
e600 does not have a bootpg restriction. Move the version string to beginning of image at fff00000. Resetvec.S is not needed. Update flash copy instructions. Add tftpflash env variable Signed-off-by: Ed Swarthout <Ed.Swarthout@freescale.com> Signed-off-by: Jon Loeliger <jdl@freescale.com>
