I agree that there is probably a far amount of code in lib_ppc/bootm.c that can be made common above it. The ARCH specific bits seem to be the "jump" and the specific mechanism to pass boot information to the kernel (bd_t, fdt, ARM tags, etc). - k ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ U-Boot-Users mailing list U-Boot-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/u-boot-users
