From 67910db907fb3d5feacdbfaa40952a88f673795a Mon Sep 17 00:00:00 2001 From: Marshall Dawson Date: Fri, 1 Nov 2019 17:30:05 -0600 Subject: arch|cpu/x86: Add Kconfig option for x86 reset vector Prepare for an implementation supporting the reset vector in RAM and not the traditional 0xfffffff0. Add a Kconfig symbol that can be used in place of hardcoded values.
