Actually, i had forgotten this mail...When i check the patches, first i'm looking at patchwork.
And I'm remembering what i do and need. Right, it's my mistake for forgetting it.

Disappearing for months/years? If i decided to do nothing, i might not reply anything to u-boot mailing list.
If you send the polite reminding ping mail, maybe i will really apologize to you. but now i don't have those mind.
You're regarding to me like nothing to do...

I'm preparing to covert to DM from legacy..For converting DM, I'm doing step by step for samsung SoCs.
Goni -> Universal210 - > Trats -> Trats2 -> Odroid also..
You can see my patches for goni, universal210, trats..

I'm not sure this problem is fixed or not..if you want to fix it, i will do it..but not right now.
I keep going my current task..

Jaehoon Chung
