mpc85xx: Update linker scripts for Freescale boards
* Move to using absolute addressing always. Makes the scripts a bit more portable and common * Moved .bss after the end of the image. These allows us to have more room in the resulting binary image for code and data. * Removed .text object files that aren't really needed * Make sure _end is 4-byte aligned as the .bss init code expects this. (Its possible that the end of .bss isn't 4-byte aligned) Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
