说明：  重点讲讲kernel移植方面的，围绕这几个问题，来讨论： 为什么要移植？ 什么时候，可以不作移植，就可以直接把kernel run到板子上？ 怎么移植？ 我们mxic要做移植是作哪个层次的移植？ 移植的时候 ，代码要改动多少？ 也就是移植的难度和工作量？
(The focus of talk about the kernel transplantation, and around this a few questions for discussion: Why should we transplant? At any time, can not be transplanted, they can directly to the kernel run on the board? How transplant? We do mxic transplant is the transplantation for what level? Transplantation when the number of code to be changed? Transplantation is the difficulty and workload?)
