- 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).
- Fixes: 8e01fb15b8157 ("arm64: dts: mt7986: add Bananapi R3")
