We are trying to debug a DDR3 issue on a custom AM4378 board. A question came up regarding the DDR configuration tool.
SITARA-DDR-CONFIG-TOOL
The tool generates the configuration register values that the user then uses in u-boot. The question is, the tool generates 36 register values for the PHY, EMIF4D_DDR_PHY_CTRL_1 thru 36. However, the register structure in u-boot only has a small subset of these registers.
https://github.com/u-boot/u-boot/blob/master/board/ti/am43xx/board.c
So what about all those extra PHY control registers the tool generated? Since there's nowhere to specify them in u-boot, do they go unprogrammed? Is this a problem?
Thanks
