Message:

If we boot from NOR, the exception vectors are provided by the NOR as well.
Once the AUX button is released, SteppingStone? appears at address 0, giving
us invalid exception vectors. Thus, any subsequent interrupt would crash
the system. This patch makes u-boot wait until AUX is released, copies the
exception vectors into SteppingStone?, and only then proceeds to enable
interrupts.

nor-irqvec.patch:

• board/neo1973/gta02/gta02.c (board_late_init): moved "extern"s to global scope, since they're now also used by board_init
• board/neo1973/gta02/gta02.c (board_init): if booting from NOR, wait until the AUX button is released
