[v6 04/10] platform/x86/amd/hsmp: Move structure and macros to header file

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is in preparation to splitting ACPI and platform device drivers.
No logical change, move common structures, macros to hsmp.h,
add missed header files, remove unwanted header inclusions,
and re-order the header file in hsmp.c file.
