This is the v2 set for supporting LPDDR4 with associated features, wrt to previous series[1]. 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 Changes for v2: - handle LPDDR4 code as part of CONFIG_RAM_RK3399_LPDDR4 - support data_training and set_rate via sdram_rk3399_ops - add proper sys_reg_enc macros - add new patch to rename variable sdram_params with params - fix few commit messages patch 0001 - 0034: fix code warnings, prints, new macros patch 0035 - 0052: rank detection, sdram debug code patch 0053: use DDR3-1800 on NanoPI-NEO4 patch 0054 - 0094: lpddr4 support patch 0095: enable lpddr4 in Rockpro64 patch 0096: enable lpddr4 in Rock-PI-4 patch 0097: LPDDR4-100 timings patch 0098: Use LPDDR4-100 on Rockpro64 patch 0099: Use LPDDR4-100 on Rock-PI 4 Size (increased to ~3KiB ): - Puma RK3399 (u-boot-spl-dtb.bin): before: 115644 after: 118744 - NanoPI M4 (u-boot-tpl-dtb.bin) before: 41873 after: 44909 Travis-CI: https://travis-ci.org/openedev/u-boot-amarula/builds/546597944 Repo: https://github.com/openedev/u-boot-amarula/tree/rk3399-lpddr4 [1] https://patchwork.ozlabs.org/cover/1113893/ Any inputs?
