From 330728d711d12f7f416b34d1598942e8c19a2724 Mon Sep 17 00:00:00 2001 From: Bin Meng <bmeng.cn@gmail.com> Date: Thu, 13 Aug 2015 00:29:07 -0700 Subject: [PATCH] x86: doc: Update coreboot payload entry point address With recent EFI support, the entry point address of coreboot payload was changed. Now we update the address to use _x86boot_start, which is the same one for EFI.
