An issue can emerge, when their size\nexceeds 16MB - in such case the kernel driver will switch automatically\nto 4B addressing mode. Later, in case of soft reset, the Boot ROM\nwill fail to fetch the firmware during the board initialization.\n\nIn order to prevent such behavior, this patch forces 3B addressing\nmode used on affected boards by adding newly introduced\n'spi-3byte-addressing' property to the SPI flash nodes.\n\nSigned-off-by: Marcin Wojtas <mw@semihalf.com>\n---\n arch/arm64/boot/dts/marvell/armada-7040-db.dts | 1 +\n 1 file changed, 1 insertion(+)", "diff": "diff --git a/arch/arm64/boot/dts/marvell/armada-7040-db.dts b/arch/arm64/boot/dts/marvell/armada-7040-db.dts\nindex 92c761c..d0bd296 100644\n--- a/arch/arm64/boot/dts/marvell/armada-7040-db.dts\n+++ b/arch/arm64/boot/dts/marvell/armada-7040-db.dts\n@@ -116,6 +116,7 @@\n \t\tcompatible = \"jedec,spi-nor\";\n \t\treg = <0x0>;\n \t\tspi-max-frequency = <20000000>;\n+\t\tspi-3byte-addressing;\n \n \t\tpartitions {\n \t\t\tcompatible = \"fixed-partitions\";\n", "prefixes": [ "2/2" ] }
