When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to make sure they can be included from user-space.
Currently, header.h and fw.h are excluded from the test coverage. To make them join the compile-test, we need to fix the build errors attached below.
For a case like this, we decided to use __u{8,16,32,64} variable types in this discussion:
these files are shared with the SOF project and used as is (with minor formatting) for the firmware compilation. I am not sure I understand the ask here, are you really asking SOF to use linux-specific type definitions?
