As there is only a single Make target, please add RAM_TEXT and
CONFIG_NAND_U_BOOT unconditionally to your config.mk and simplify the
Makefile entry here.

All this seems to be not needed since you have a single, static
configuration anyway.

This seems to be not needed as only board/gec/gec2410/lowlevel_init.S
will include any file from there, and then they are in the same
directory.

Such #defines have no place in the source code. Please move to
appropriate header file.

You probably do not want to do this, or at least not call it delay().

It's hard to make a program foolproof because fools are so ingenious.
