[U-Boot] MAKEALL ml507_flash return "Not enough room for programheaders" error

[Benny Chen]

Hi Ricardo,
Changing my tool chain to the ELDK 4.2 ppc-linux-x86 does build the
default ml507_flash project.  However, because my hardware design does
not map the FLASH chip to 0xFE000000 but to 0x86000000 the build failed
with the following error.

/******************************/
cpu/ppc4xx/start.o: In function `rsttlb':

/usr/local/groundprobe/src/Bootloader/u-boot/cpu/ppc4xx/start.S:493:
relocation truncated to fit: R_PPC_REL24 against symbol `_start' defined
in .text section in cpu/ppc4xx/start.o
/*****************************/

I think this issue maybe to do with the 24bit branch address limit with
the PPC440x5 core. Here the _start_440 function calls a "b _start" and
in this case the _start is mapped to flash in address 0x8600xxxx.
Meaning we now need to branch from 0xFFFFFxxx to 0x8600xxxx.  I think
this is why the linker failed at the last stage.

Does anyone have any idea with this issue?

Regards,
Benny

Hello Benny

  I have just checkout the build of the ml507_flash and works ok for me

ricardo at aragorn:~/curro/qtec/u-boot$ ./MAKEALL ml507_flash
Configuring for ml507 board...
   text	   data	    bss	    dec	    hex	filename
 202132	  10476	  30032	 242640	  3b3d0	./u-boot


  I remember that when I was using another toolchain the final link
failed (but showing different error). Try with another toochain, I am
using one produced by OpenEmbedded, but you will get the same results
with the ELDK


  Best regards
