From 28cee59ca294422056d983fc06d5d8d5800a4390 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Thu, 8 Mar 2018 15:43:12 +0100 Subject: drivers/vpd: Add VPD support VPD reference: https://chromium.googlesource.com/chromiumos/platform/vpd/+/master/README.md Copy ChromeOS VPD driver to add support for VPD without CROMEOS. Possible use case: * Storing calibration data * Storing MAC address * Storing serial * Storing boot options + Now it's possible to define the VPD space by choosing one of the following enums: VPD_ANY, VPD_RW, VPD_RO. + CHROMEOS selects now VPD as part of it. + VPD is implemented as driver.
