Linux 2.6 from git.xilinx and XUPV2P

[greenlean]

OK, now this morning (I'm working in Spain) I compiled the kernel using the
xparameters_xupv2p.h generated by edk, everything is OK, only a few
warnings. 

But as I told you yesterday I have the same problem, the xdm shell tell me
that it can't read the file, maybe it is corrupted, the error reported is
the ERROR(1053) I don't Know what it means.

Following your steps I try to verify that the elf file generated is an elf
file, I used the ppc_4xx-readelf -h zImage.elf command and it told me this
result:

$ppc_4xx-readelf -h arch/ppc/boot/images/zImage.elf
ELF Header:

  Size of this header:               52 (bytes)
  Size of program headers:           32 (bytes)
  Number of program headers:         2
  Size of section headers:           40 (bytes)
  Number of section headers:         17
  Section header string table index: 14

I'm not sure about what I supossed to do with objdump, any instruction about
what to look for,  because objdump works fine, it show me the instruction.

I'm going to search about the elf file, to ensure this is a good elf file.
