 Hi,

   Trying to run the u-boot for taihu board within qemu.  but i get some error.

    I am using  u-boot-latest and qemu-1.6.1.  

    Command:  
   make distclean
   make mrproper
   make ARCH=powerpc CROSS_COMPILE=/tools/bin/powerpc-linux-   taihu_defconfig
   make ARCH=powerpc CROSS_COMPILE=/tools/bin/powerpc-linux-
  dd if=/dev/zero of=flash.img bs=1M count=512
  dd if=u-boot.bin of=flash.img conv=notrunc
  qemu-system-ppc -M taihu -m 200 -nographic -pflash flash.img
  
  then i get 
   taihu_405ep_init: register cpu
   ppc4xx_opba_init: offset 00000000ef600600
   ppc405_gpio_init: offset 00000000ef600700

   How can I solve the error?
  Your feedback would help me a lot.

 Thanks in advance,
