I found the stupid mistake. I copy the entire directory and forget to modify the Makefile inside. just rename the $(ORIG_BOARD).c to $(NEW_BOARD).c since there is a line in Makefile: OBJS = $(BOARD).o. There is no mercury.c so make is unhappy. However the make give me confusing messages. Hope this mail be helpful to other newbies.
It's adapted from the evaluation board.

I am newbie. I am trying to port u-boot to my board. I did these things: 1. copy a existing board directory, say m5445evb, to a new one "mercury" 2. copy the M5445X_config section and rename it to "MERCURY_config" 3. change board name "m5445evb" in the "@mkconfig -a ..." lineto mercury but when I try to compile u-boot make says "no rule to make target .depend", needed by lib_mercury.a in the board/freescale/mercury directory. I can compile u-boot for m5445evb normally. What's the matter?
You failed to adapt board/freescale/mercury/Makefile to your new board. Are you sure this is indeed a Freescale board? If not, then why is it located in the Freescale vendor directory?
