FRWY-LS1046A-AC DDR4配置咨询

[tian_shuliang]

想确认下：

1.使用FRWY-LS1046A-AC单板的代码是否可以兼容DDR4（MT40A1G16RC-062E）芯片？如果兼容，DDR4是否有降频的可能？

2.如果不兼容，是否有DDR4（MT40A1G16RC-062E）时序配置的相关patch？

3.如果没有patch，确认下是否只修改参数ddr_raw_timing（路径：packages/firmware/atf/plat/nxp/soc-ls1046/ls1046afrwy/ddr_init.c）即可？

1,2. The LS1046A supports DDR4 only. So yes, it is compatible with DDR4 in general and with MT40A1G16RC-062E in particular.

3. Yes, you can modify ddr_raw_timing in accordance with the new memory parameters.
