As I'm not a ARM specialist, I have several questions.
Does porting to ARM11 (ARVv6, am I right?) will make porting to ARMv7 (Cortex) easier? You see, i486 adds some nice commands, tricks and configuration registers to i386, but porting to i486 after you have working port to i386/Protected mode is almost trivial. Or it is completely different architectures, which doesn't have anything in common? ARMvX is only a core, as far as I understand. How much different are implementations from different vendors? MMU? Bus? Configuration space? Why do you think, porting to different ARMs should go sequentially? :) Yes, we (FreeBSD) doesn't have a lot of resources, but as nobody could be forced to do what he don't want, it is better, IMHO, to have ARM11 port, that to not have any ARM port at all. But I agree, that port to Cortex-A8/A9 looks more interesting :) -- // Black Lion AKA Lev Serebryakov <l...@freebsd.org> _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
