Including this in meta-xilinx-bsp would be fine since it is a generally available board and low cost as well. However I am not sure it would be worth including if it relies on adding support with patches. It would be best if those parts were upstreamed to U-Boot/Linux first then adding the patches as backports if required. > > --- > meta-xilinx-bsp/conf/machine/zturn-zynq7.conf | 34 + > .../recipes-bsp/platform-init/platform-init.bb | 1 + > .../platform-init/zturn-zynq7/ps7_init_gpl.c | 13170 > +++++++++++++++++++ > .../platform-init/zturn-zynq7/ps7_init_gpl.h | 137 + > .../0001-Add-device-tree-for-z-turn-board.patch | 170 + > .../recipes-kernel/linux/linux-xlnx.inc | 2 + > 6 files changed, 13514 insertions(+) > create mode 100644 meta-xilinx-bsp/conf/machine/zturn-zynq7.conf > create mode 100644 > meta-xilinx-bsp/recipes-bsp/platform-init/platform-init/zturn-zynq7/ps7_init_gpl.c > create mode 100644 > meta-xilinx-bsp/recipes-bsp/platform-init/platform-init/zturn-zynq7/ps7_init_gpl.h > create mode 100644 > meta-xilinx-bsp/recipes-kernel/linux/files/0001-Add-device-tree-for-z-turn-board.patch > > diff --git a/meta-xilinx-bsp/conf/machine/zturn-zynq7.conf > b/meta-xilinx-bsp/conf/machine/zturn-zynq7.conf > new file mode 100644 > index 0000000..edac836 > --- /dev/null > +++ b/meta-xilinx-bsp/conf/machine/zturn-zynq7.conf > @@ -0,0 +1,34 @@ > +#@TYPE: Machine > +#@NAME: zybo-zynq7 > +#@DESCRIPTION: Machine support for ZYBO. > +# > +# For details on the ZYBO board: > +# https://www.digilentinc.com/Products/Detail.cfm?Prod=ZYBO > +# Make sure to update this documentation.

You will likely want to clean up the file so its smaller and similar to the existing ps7_init_gpl.c files in the U-Boot source. It appears that Alexander Graf intended to submit this part but I don't see any patches on the U-Boot patchwork. https://patchwork.ozlabs.org/patch/783430/ <-- trimmed--> > diff --git > a/meta-xilinx-bsp/recipes-kernel/linux/files/0001-Add-device-tree-for-z-turn-board.patch > > b/meta-xilinx-bsp/recipes-kernel/linux/files/0001-Add-device-tree-for-z-turn-board.patch > new file mode 100644 > index 0000000..fe00e6c > --- /dev/null > +++ > b/meta-xilinx-bsp/recipes-kernel/linux/files/0001-Add-device-tree-for-z-turn-board.patch > @@ -0,0 +1,170 @@ > +From 1db3fb1c6103ce8c2836f9e42a8799efaea8cf0d Mon Sep 17 00:00:00 2001 > +From: Anton Gerasimov <anton.gerasi...@openmailbox.org> > +Date: Sun, 4 Mar 2018 17:53:00 +0100 > +Subject: [PATCH] Add device tree for z-turn board > + > +--- > + arch/arm/boot/dts/zynq-zturn-myir.dts | 151 > ++++++++++++++++++++++++++++++++++ > + 1 file changed, 151 insertions(+) > + create mode 100644 arch/arm/boot/dts/zynq-zturn-myir.dts > + > +diff --git a/arch/arm/boot/dts/zynq-zturn-myir.dts > b/arch/arm/boot/dts/zynq-zturn-myir.dts > +new file mode 100644 > +index 000000000000..8648d9cacaa5 > +--- /dev/null > ++++ b/arch/arm/boot/dts/zynq-zturn-myir.dts > +@@ -0,0 +1,151 @@ > ++/* > ++ * Copyright (C) 2015 Andrea Merello <adnrea.mere...@gmail.com> andrea.mere...@gmail.com > ++ * > ++ * Based on zynq-zed.dts which is: > ++ * Copyright (C) 2011 - 2014 Xilinx > ++ * Copyright (C) 2012 National Instruments Corp. > ++ * > ++ * This software is licensed under the terms of the GNU General Public > ++ * License version 2, as published by the Free Software Foundation, and > ++ * may be copied, distributed, and modified under those terms. > ++ * > ++ * This program is distributed in the hope that it will be useful, > ++ * but WITHOUT ANY WARRANTY; without even the implied warranty of > ++ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
