From f7855bb7dbdbabafa86a624cd8450129d99514cb Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 2 Oct 2018 07:39:29 -0700 Subject: [PATCH] efi_loader: Generate Microsoft PE format compliant images Per Microsoft PE Format documentation [1], PointerToSymbolTable and NumberOfSymbols should be zero for an image in the COFF file header. Currently U-Boot is generating *.efi images (eg: helloworld.efi) in which these two members are not zero. This updates the build rules to tell linker to remove the symbol table completely so that we can generate compliant *.efi images.
