[U-Boot-Users] MIPS (purple) compilation problems.

[Ronen Shitrit]

Hi

I'm trying to port the U-Boot to Marvell board with MIPS (rm7000)
I am using a cross compiler mips64-elf.
I'm trying to compile the purpule_config and I have some compilation 
problems,
when I'm using the cpu/mips/config  flag -mabicalls I get a lot of warnings:
      c1: warning: -G is incompatible with PIC code which is the default
       .........
and an LD error:
      mips64-elf-ld: common/main.o: linking PIC files with non-PIC files
      Bad value: failed to merge target specific data of file common/main.o

When I remove the -mabicalls flag, the compilation pass, and the LD fail 
again on different error:
        mips64-elf-ld: target elf32-tradbigmips not found

The LD is looking for elf32-tradbigmips because in the LD script we 
define the output file to be: elf32-tradbigmips

why do we use this definition and not elf32-bigmips??  and what is the 
difference between these two??
and why when I install my cross compiler I don't have support for this 
output format??

so I changed it the output format to elf32-bigmips then I'm getting this 
LD error:
            : undefined reference to `_GLOBAL_OFFSET_TABLE_'

I know it is because I don't have this define in the linker script, and 
I guess the elf32-tradbigmips has this definition.
What should I do??

Thanks
