At present, run upstream qemu 2.1.2 and upstream Linux kernel 3.17-rc7
with simple ramfs successfully. Via modify ramfs, can run hello world
program with static glibc (built by upstream mc_gcc), successfully.

 - For ramfs:

   wget http://www.wiki.xilinx.com/file/view/microblaze_complete.cpio.gz/419243588/microblaze_complete.cpio.gz

 - Related qemu command:

   ./microblaze-softmmu/qemu-system-microblaze -M petalogix-s3adsp1800 \
     -kernel ../linux-stable.microblaze/arch/microblaze/boot/linux.bin \
     -no-reboot -append "console=ttyUL0,115200 doreboot" -nographic

Next, I shall try to let our gdb and DejaGNU work for it:

 - How to let qemu support network and rsh (ramfs need telnetd, kernel
   may need related driver, and qemu related hardware need be tested).

 - Let gdb work for it, then config DejaGNU (need we test the program
   with dynamic glib, it will be fail now for not match glibc version
   in ramfs).

 - At last, run our test.

It seems, still many things need trying. Welcome any ideas, suggestions,
and completions for it (especially for ramfs network and/or glibc, and
DejaGNU configuration ...).


Thanks.
