Aside from needing to migrate a few symbols to Kconfig, to build on current master, we need to: > diff --git a/include/configs/starqltechn.h b/include/configs/starqltechn.h > new file mode 100644 > index 00..c9736a443b > --- /dev/null > +++ b/include/configs/starqltechn.h > @@ -0,0 +1,16 @@ > +/* SPDX-License-Identifier: GPL-2.0+ */ > +/* > + * Board configuration file for Samsung S9(SM-G9600)(starqltechn) > + * > + * (C) Copyright 2017 Jorge Ramirez-Ortiz > + */ > + > +#ifndef __CONFIGS_STARQLTECHN_H > +#define __CONFIGS_STARQLTECHN_H > + > +#include > + > +#define CONFIG_LNX_KRNL_IMG_TEXT_OFFSET_BASECONFIG_SYS_LOAD_ADDR > +#define CONFIG_LINUX_KERNEL_IMAGE_HEADER These two symbols need to be handled via Kconfig (xenguest_arm64 gets this wrong as well, I see) as done for example on Tegra. At that point, we can delete this file entirely and just use configs/sdm845.h. -- Tom signature.asc Description: PGP signature

Hi! I haven't tried to install u-boot on the phone with Android boot image yet(though another guy in the community project I contribute, reported it works). I can only test u-boot with kexec, it's the only way to get debug uart for me, without disassembling the phone. Also I have to track down the issues with booting linux. So, once I'll got linux booted by u-boot, I will be able to pack and install it in Android boot partition, and write more detailed instructions. пт, 24 сент. 2021 г. в 14:02, Stephan Gerhold : > Hi, > > On Thu, Sep 23, 2021 at 09:57:32PM +0300, dsankou...@gmail.com wrote: > > From: Dzmitry Sankouski > > > > Samsung S9 SM-G9600 - Snapdragon SDM845 version of the phone, > > for China \ Hong Kong markets. > > Has unlockable bootloader, unlike SM-G960U (American market version), > > which allows running u-boot as a chain-loaded bootloader. > > > > Signed-off-by: Dzmitry Sankouski > > Cc: Ramon Fried > > Cc: Tom Rini > > --- > > Changes for v2: > > - Create documentation file for SDM845 boards > > - Add starqltechn board documentation > > Changes for v3: > > - fix comment in starqltechn.c > > > > arch/arm/dts/Makefile | 1 + > > arch/arm/dts/starqltechn-uboot.dtsi | 39 ++ > > arch/arm/dts/starqltechn.dts| 53 + > > arch/arm/mach-snapdragon/Kconfig| 13 ++ > > board/samsung/starqltechn/Kconfig | 14 +++ > > board/samsung/starqltechn/MAINTAINERS | 6 +++ > > board/samsung/starqltechn/Makefile | 9 + > > board/samsung/starqltechn/starqltechn.c | 10 + > > configs/starqltechn_defconfig | 33 +++ > > doc/board/qualcomm/index.rst| 1 + > > doc/board/qualcomm/sdm845.rst | 38 ++ > > include/configs/starqltechn.h | 16 > > 12 files changed, 233 insertions(+) > > create mode 100644 arch/arm/dts/starqltechn-uboot.dtsi > > create mode 100644 arch/arm/dts/starqltechn.dts > > create mode 100644 board/samsung/starqltechn/Kconfig > > create mode 100644 board/samsung/starqltechn/MAINTAINERS > > create mode 100644 board/samsung/starqltechn/Makefile > > create mode 100644 board/samsung/starqltechn/starqltechn.c > > create mode 100644 configs/starqltechn_defconfig > > create mode 100644 doc/board/qualcomm/sdm845.rst > > create mode 100644 include/configs/starqltechn.h > > > > [...] > > diff --git a/doc/board/qualcomm/sdm845.rst > b/doc/board/qualcomm/sdm845.rst > > new file mode 100644 > > index 00..cd46cbe9cf > > --- /dev/null > > +++ b/doc/board/qualcomm/sdm845.rst > > @@ -0,0 +1,38 @@ > > +..

You say that it is loaded through an Android boot image, but how exactly is it built? For example, do you use an empty ramdisk, does the bootloader expect some dt.img etc? Something similar to the DB820c README: https://source.denx.de/u-boot/u-boot/-/blob/master/board/qualcomm/dragonboard820c/readme.txt#L32-61 This would be helpful if someone wants to install U-Boot on that phone I think :) Thanks!
