commit 0e0988b971e46234198bd6e3945d20e6532ffddf Author: ZhengShunQian zhengsq@rock-chips.com Date: Fri Oct 28 16:16:04 2016 +0800
google/veyron*: change .ddrconfig from 14 to 3
There are two configs, sdram-lpddr3-hynix-2GB.inc and sdram-lpddr3-samsung-2GB-24EB.inc that use .ddrconfig = 14.
Changing .ddrconfig from 14 to 3 improves performance especially on contiguous memory accesses. Comparing the .ddrconfig: - if .ddrconfig = 3, C RDRR RRRR RRRR RRRR RBBB CCCC CCCC C--- - if .ddrconfig = 14, C DRBB BRRR RRRR RRRR RRRR CCCC CCCC C--- where - R: indicates Row bits - B: indicates Bank bits - C: indicates Column bits - D: indicates Chip selects bits
.ddrconfig = 3 has multiple banks switching which improves DDR timing.
