Your correct this line doesn't give a waring. The toolchain is ELDK
4.2. But the warning is "only" in line 219:

[stefan at kubuntu u-boot (master)]$ ./MAKEALL hcu4
Configuring for hcu4 board...
jedec_flash.c:219: warning: large integer implicitly truncated to unsigned type

Some of the manufacturer defines are defined (again) 16bit wide
in jedec_flash.c, and one (STM_MANUFACT) is defined 32bit wide
in include/flash.h (0x00200020). 

Perhaps its better to remove those double manufacturer defines from
jedec_flash.c? Just let me know if you would prefer such a version
and I will generate a patch for it.

Best regards,
Stefan
