This patch-set is to support eMMC HS200 and HS400 speed modes for
eSDHC, and enable them on LX2160ARDB board.

Is there any result about performance?

Hi Jaehoon,

Below is the full log of the performance and function tests for eMMC HS400 mode. Since I used date to record time, there must be some error more or less.
I tested the r/w performance with 4G data size at 175MHz bus speed. The results were,
Read: 273MB/s = 4096MB / 15s
Write: 74MB/s = 4096MB / 55s

According to the eMMC data sheet the HS400 max performance for sequential r/w are,
Read: 270MB/s
Write: 90MB/s

The performance seems to be matched and good.
BTW, the test was applied two more patches to fix stability issue. Let me send out v2 patch-set with them.
Thanks.
