From 032c226bc6de2be0d5c88940ca7534a80cf0dd1a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Tue, 26 Jan 2021 18:10:59 +0100 Subject: [PATCH] ppc/pnv: Introduce a LPC FW memory region attribute to map the PNOR MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This to map the PNOR from the machine init handler directly and finish the cleanup of the LPC model.
