Great, this patch will let us to play with ftrace in fsl-imx51.
And just one comment, could you please add the BugLink info and cherry-pick 
comments into this commit? just like this, 
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-lucid.git;a=commit;h=29c60ccc1a408371885d79d8f8c081fbcb9b10be

And one more question, need we enable the CONFIG_FTRACE_* in fsl-imx51 config?
