请教一下MPC8560的linux编译问题，谢谢！

beyond291

根据powerpc的linux介绍，ARCH=ppc的分支不再维护了，ARCH=powerpc是以后的发展方向。
只是目前ppc往powerpc的转移还没有完成，所以编译powerpc的linux存在两种方式。
我在公司移植过linux2.6.24到MPC8349的单板上，只能使用ARCH=ppc来编译才可以，用ARCH=powerpc
则编译后无法运行，经过初步定位在setup_32.s里边的CPU初始化就失败了，可能转移还没有完成吧。
最近特想玩玩MPC8560，没有硬件环境，只能在模拟器里玩，skyeye支持MPC8560，所以想尝试一下，
但是遇到了些问题：
我用ARCH=powerpc的方式编译出来的内核，用skyeye运行，出现如下情况：

如果我用ARCH=ppc编译，则编译不通过，信息如下：

所有的配置都没有修改，直接用mpc8560_ads_defconfig配置文件。
不知道skyeye的testcase里mpc8560的linux内核是怎么生成的？还请skyeye的高手们指导一下，谢谢！！！

另外，我们对powerpc的模拟又fix了一些bug,如果你使用最新版本，则可以运行不加修改kernel任何代码的image文件。相关信息请看：http://lists.gro.clinux.org/pipe ... 08-June/001817.html

我们在六月中旬开始模拟powerpc双核的mpc8572，也希望对powerpc有一定基础的，并且感兴趣的朋友一起参与。

出来，运行的时候还是像楼主一模一样的情况啊，还是停在那里，我用的initrd.img是test case 里面直接拷过来的，因为我没有这个文件，请问，可以这样吗？
