I got an answer based on the other question I had posted.

I think "Rule" provided for given inf (using RuleOverride) forces certain files to be present:

[Rule.Common.USER_DEFINED.ACPITABLE]
FILE FREEFORM = $(NAMED_GUID) {
RAW ACPI |.acpi
RAW ASL |.aml
}

So, in this case, for given inf module, if either of .acpi or .aml file is not generated,

then below kind of error shows up:

: error F003: Output file for RAW section could not be found for Platform/ARM/JunoPkg/AcpiTables/AcpiTables.inf

Hi All,

I am trying to compile some ACPI tables, and I observed that
if I specify less minimal tables/asl as Sources for ACPI tables module INF file
(resulting in less size of overall module), compilation fails with below error:

build.py...
: error F003: Output file for RAW section could not be found for Platform/ARM/JunoPkg/AcpiTables/AcpiTables.inf

To reproduce this issue,
1) Apply below patch (just keeping Fadt.c here as example;
Other ways: just keep ASL file after removing some objects to reduce file size; or keep combination of .c and .asl files - **as long as these files are small**):
