imx6 kernel3.10 kernel3.14 kernel4.1.15 （console [ttymxc0] enabled） too slow issue

[昌清黄]

I  find kernel booting on imx6,  register console very slow（console [ttymxc0] enabled）.

I find the following versions of kernel（kernel3.10.53  3.14  4.1.15） all have this problem.

please check the log（when console  enabled）。

Hi

            thanks！I still can't find a way to solve the problem！ I think this problem exists in later versions of 3.10。

            I review this：
