Hi Xianwei,

I am doing the basics for Amlogic T7 A311D2, but the next step ( sd
card or emmc, something to boot on) would be more difficult for me
than you.
After the first series for Vim4 gets merged, I will start to work on
how to get sd cards working.
But if you already have that working for the AN400 board, please send
it. And I will look at that work and use it for Vim4.

Or, if you don't have it ready and want to share it with me, we can
work together on these A311D2 patches.
You test on AN400, and I test on Vim4.

Thanks
Lucas
