From 6dd3b939370094eb79529683be84500f3c757404 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Tue, 6 Jun 2023 16:43:20 +0100 Subject: [PATCH 19/19] arm64: dts: mt7986: increase bl2 partition on NAND of Bananapi R3 The bootrom burned into the MT7986 SoC will try multiple locations on the SPI-NAND flash to load bl2 in case the bl2 image located at the the previously attempted offset is corrupt. Use 0x100000 instead of 0x80000 as partition size for bl2 on SPI-NAND, allowing for up to four redundant copies of bl2 (typically sized a bit less than 0x40000).
