   4 Subject: [PATCH 19/19] arm64: dts: mt7986: increase bl2 partition on NAND of
   5  Bananapi R3
   6
   7 The bootrom burned into the MT7986 SoC will try multiple locations on
   8 the SPI-NAND flash to load bl2 in case the bl2 image located at the the
   9 previously attempted offset is corrupt.
  10
  11 Use 0x100000 instead of 0x80000 as partition size for bl2 on SPI-NAND,
  12 allowing for up to four redundant copies of bl2 (typically sized a
  13 bit less than 0x40000).
