From 5998c8f059dbd64c5391e4caec2c07d434ffe146 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=81lvaro=20Fern=C3=A1ndez=20Rojas?= Date: Thu, 21 May 2020 15:04:23 +0200 Subject: bcm63xx: nand: support CFE partition tags MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce support for generating JFFS2 CFE partition tags. This is used in NAND devices in order to verify the integrity of the JFFS2 partition.
