From 3217cdfe8a3eae76fafbebbe407be5985a7fd4c2 Mon Sep 17 00:00:00 2001 From: Tomasz Maciej Nowak Date: Mon, 31 Dec 2018 14:18:50 +0100 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 SPI 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" string with proper one. The second is linked to partitions layout, it changed after commit [1] in Marvells downstream U-Boot fork, shifting environment location to the end of boot device. Since the new boards can have U-Boot with this change it can lead to improper results writing or reading from these partitions. We can't tell if users will update bootloader to recent version, so let's drop current layout. 1. https://github.com/MarvellEmbeddedProcessors/u-boot-marvell/commit/81e7251252aefe1a6b829ed05f3586320cb45372 Signed-off-by: Tomasz Maciej Nowak --- .../dts/marvell/armada-3720-espressobin.dts | 18 +----------------- 1 file changed, 1 insertion(+), 17 deletions(-) --- a/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts +++ b/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts @@ -127,25 +127,9 @@ 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>; - }; - }; }; };
