Quoted 4 lines

Add support for mcf5307 coldfire cpu. This is the updated entire patch, tested on a mcf5307 based custom board. Only this new set of file has been added, no other files in the tree are involved.

[Jin Zhengxiong-R64188] We at least need to update the Makefile or boards.cfg for the new added cpu/board? Or add some descriptions for how to configure and build the board? Thanks.

[Jin Zhengxiong-R64188] Please try to use checkpatch to clean up the patch, there are a lot of coding style warnings and errors. Thanks.
