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

Tue Jun 11 14:50:03 UTC 2019

Yes, it can be possible to break this series into multiple sub series
but idea here is to mark all the required changes to support LPDDR4 
in rk3399 in one set. if required we can break it from next versions.

This is the initial set for supporting LPDDR4 with associated
features.

Thanks to
- YouMin Chen
- Akash Gajjar
- Kever Yang
for supporting all the help on this work.

On summary this series support
- Code warning and fixes
- rank detection, this would required to probe single channel 
  sdram configured in NanoPI-NEO4
- LPDDR4 support, tested in Rockpro64 and Rock-PI-4

patch 0001 - 0033: fix code warnings, prints, new macros

patch 0034 - 0051: rank detection, sdram debug code

patch 0052: Use DDR3-1800 on NanoPI-NEO4

patch 0053 - 0089: lpddr4 support

patch 0090: LPDDR4-100 timings

patch 0091: Use LPDDR4-100 on Rockpro64

patch 0092: Use LPDDR4-100 on Rock-PI 4

Note: Puma rk3399 has SPL size overflow, better to enable TPL
for this board.

Any inputs?
Jagan.
