nor-bootmenu.patch
This patch makes u-boot on GTA02 always enter the bootmenu when booting from
NOR. This de-complexifies interaction with the user and is actually also
needed for correctly handling the exception vectors.
- cpu/arm920t/start.S (booted_from_nor): set this flag if booting from NOR
- board/neo1973/gta02/gta02.c (board_late_init): always enter the boot menu if
booting from NOR
- board/neo1973/gta02/gta02.c (board_late_init): used the opportunity to place
the "extern"s at a more prominent location
