From 1717231b74ed7aad3e38afb2b3e569fa5459eb3a Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Fri, 1 Jan 2021 14:08:29 -0600 Subject: [PATCH] drivers/vpd: Add VPD region to default FMAP when selected MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently, use of the VPD driver to read VPD tables from flash requires the use of a custom FMAP with one or more VPD regions. Extend this funtionality to boards using the default FMAP by creating a dedicated VPD region when the driver is selected. Test: build qemu target with CONFIG_VPD selected, verify entry added to build/fmap.fmd.
