-Auto-detect whether we're booting from RAM or NAND, and act accordingly. This
-allows us to use the same u-boot binary for all boot modes.
-
-include/configs/neo1973.h: introduced new config option
- CONFIG_LL_INIT_NAND_ONLY to perform low-level initialization only when
- booting from NAND
-include/configs/neo1973.h: got rid of BUILD_FOR_RAM
-cpu/arm920t/start.S: detect if we need to boot from NAND at run time (i.e., if
- we're running at address 0)
