Linux on SAMSUNG s3c2443

我移植linux kernel 2.6.26.2到三星s3c2443处理器上，当我一直完，linux kernel已经更新到2.6.26.5了。不过其间的修改没有影响到s3c244x处理器系列。
总的来说，kernel2.6.26.2对s3c2443的支持非常的不好，它的许多代码只是移植了s3c2410的内核代码，因此在体系结构方面只是一个框架。根本不能用。
s3c2443的更好的官方支持要等2.6.28系列内核了，就目前kernel 2.6.27-rc一直在紧急的修补当中，不过我发现没有多少kernel修改者提交针对s3c2443的补丁，可能是市面上拿到s3c2443 CPU的人比较少？！
当然kernel 2.6.26.2经过修改已经可以启动，下面是我的boot log：
