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).
|
||
|
