The working code uses a value of 00b for this field. When I changed it to 11b, things broke. In the documentation, this register is defined differently for mx6q vs mv6solo/duallite. The duallite way works for the quad, and either way works for the duallite.
board/boundary/nitrogen6x/ddr-setup.cfg:DATA 4, MX6_IOM_DRAM_RESET, 0x000e0030
board/freescale/imx/ddr/mx6q_4x_mt41j128.cfg:DATA 4 0x020e057c 0x00020030
Who's right? And should it depend on quad vs duallite ? Currently, I believe that the duallite documentation is correct for all.
Both are not correct. The MMDC owner has known about this doc issue and will Update them later. The correct is: 00 is the only valid data, others will be Reserved.
Thank you very much for the concise and definitive reply.
Yes, thank you. I will send a patch for board/boundary/nitrogen6x/ddr-setup.cfg to match board/freescale/imx/ddr/mx6q_4x_mt41j128.cfg
