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.
