From 00954566464a46dbfd747aaeace281dc9eb00361 Mon Sep 17 00:00:00 2001 From: Tomasz Maciej Nowak Date: Mon, 27 May 2019 13:16:14 +0200 Subject: [PATCH] arm64: dts: armada-3720-espressobin: correct spi node The manufacturer of this board, ships it with various SPI NOR chips and increments U-Boot bootloader version along the time. There is no way to tell which is placed on the board since no revision bump takes place. This creates two issues. The first, cosmetic. Since the NOR chip may differ, there's message on boot stating that kernel expected w25q32dw and found different one. To correct this, remove optional device-specific compatible string. Being here lets replace bogus "spi-flash" compatible string with proper one. The second is linked to partitions layout, it changed after commit: 81e7251252 ("arm64: mvebu: config: move env to the end of the 4MB boot device") in Marvells downstream U-Boot fork [1], shifting environment location to the end of boot device. Since the new boards will have U-Boot with this change, it'll lead to improper results writing or reading from these partitions. We can't tell if users will update bootloader to recent version provided on manufacturer website, so lets drop partitons layout. 1. https://github.com/MarvellEmbeddedProcessors/u-boot-marvell.git Signed-off-by: Tomasz Maciej Nowak Signed-off-by: Gregory CLEMENT --- .../dts/marvell/armada-3720-espressobin.dts | 18 +----------------- 1 file changed, 1 insertion(+), 17 deletions(-) diff --git a/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts b/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts index 6be019e1888e..fbcf03f86c96 100644 --- a/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts +++ b/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts @@ -95,25 +95,9 @@ &spi0 { flash@0 { reg = <0>; - compatible = "winbond,w25q32dw", "jedec,spi-flash"; + compatible = "jedec,spi-nor"; spi-max-frequency = <104000000>; m25p,fast-read; - - partitions { - compatible = "fixed-partitions"; - #address-cells = <1>; - #size-cells = <1>; - - partition@0 { - label = "uboot"; - reg = <0 0x180000>; - }; - - partition@180000 { - label = "ubootenv"; - reg = <0x180000 0x10000>; - }; - }; }; }; -- 2.45.2
