Hi Vikas,
Sorry for the delay and thanks for clarifying.
1. OK. I was just curious why we need to override it to include fewer tables. Isn't it better to support more ACPI tables? Anyways, I'm fine with the current change because it is intended. We can discuss this later once we're done with synchronizing edk2-platform with NXP-LSDK.
2. OK, I just thought that you would like to use the same way (build flag) as what we used in NXP LSDK. I'm also fine with the current approach. We can co-work with NXP to update NXP-LSDK later.

Subject: RE: [PATCH V2 3/4] NXP/LS1046aFrwyPkg: Enable ConfigurationManager on LS1046AFRWY
Hi Vikas,
Just have two comments below. Others look good to me.
1. In LS1046aFrwyPkg.dsc, since you already include DynamicTablesPkg/DynamicTables.dsc.inc, I think we need to remove DynamicTableFactoryDxe.inf code block. Could you check this?
[[VIKAS]] No, DynamicTableFactoryDxe.inf code block Is required to override, or I would say to choose what we want for our platform from DynamicTablesPkg.
This block can expose different "inf" files for different platforms as per the need basis.
2. Remove " DEFINE DYNAMIC_ACPI_ENABLE = TRUE ". In our offline discussion, this would cause some build problems with the current CM implementation (Multiple NXP platforms share One CM folder).
[[VIKAS]] I don't think "DEFINE DYNAMIC_ACPI_ENABLE = TRUE" should cause any problem while building other platforms. In fact this flag is to avoid any build issue with other platforms. CM is common for all layer scape platforms but it will be only visible to any platform if and only if "DEFINE DYNAMIC_ACPI_ENABLE = TRUE". Else platform must be building in old native mode. Could you share any scenario or something that I have missed out, will check this implementation and try to rectify.
Best Regards,
Sunny Wang
