[U-Boot] [PATCH 00/92] ram: rk3399: Add LPDDR4 support

Thu Jun 13 01:44:16 UTC 2019

Hi Jagan,

    Very grateful for you to send this patch set for LPDDR4 support.

    But, 92 patches, a little bit too much for merge them one by one,

is it possible for U-Boot to merge this from somewhere after we review

all these patches?

Thanks,
- Kever
