Preserve hii section in GCC binaries
According to UEFI spec: Once an image is loaded, LoadImage() installs EFI_HII_PACKAGE_LIST_PROTOCOL on the handle if the image contains a custom PE/COFF resource with the type 'HII'. The protocol's interface pointer points to the HII package list which is contained in the resource's data. This is controlled by the UEFI_HII_RESOURCE_SECTION define in the INF file. When present the HII resource is linked with the module binary. Unfortunately GCC-built binaries have been stripping the .hii section entirely. See "[edk2] HII gEfiHiiPackageListProtocolGuid problem with GCC48(VS2012x86 works)" http://thread.gmane.org/gmane.comp.bios.tianocore.devel/13438 http://thread.gmane.org/gmane.comp.bios.tianocore.devel/14899 This patch tells the linker to preserve the .hii sections Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Thomas Palmer <thomas.palmer@hpe.com> Acked-by: Laszlo Ersek <lersek@redhat.com> Tested-by: Bruce Cran <bruce.cran@gmail.com> Reviewed-by: Bruce Cran <bruce.cran@gmail.com> Reviewed-by: Yonghong Zhu <yonghong.zhu@intel.com> Reviewed-by: Liming Gao <liming.gao@intel.com>
