you don't need change start.s to boot from NOR. If shold set the #define CONFIG_SYS_TEXT_BASE 0x00000000
Please see the configuration for eb_cpux9k2 board. This board does boot from NOR with u-boot 2012.10.
BTW The release 2012.10 is out of date. You should upadte to the current one (2013.10-rc4)
Best regards
