From 972ffcd7b0bef07e07e02a339bc0ae95a5d9d5b8 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 2 Oct 2018 07:39:30 -0700 Subject: [PATCH] x86: efi: payload: Generate Microsoft PE format compliant image 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 u-boot-payload.efi image 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.
