From 28144ba8d020bc5411eab8afe67cf359c8a543ef Mon Sep 17 00:00:00 2001 From: Svyatoslav Ryhel Date: Thu, 27 Jan 2022 19:42:04 +0200 Subject: [PATCH] board: asus: transformer: add ASUS Transformer T20 family support The Asus Eee Pad Transformer family are 2-in-1 detachable/slider tablets developed by Asus that run the Android operating system. The Eee Pad Transformers feature a 10.1-inch (260 mm) display, an Nvidia Tegra 2 dual-core chip, 1 GB of RAM, and 16/32 GB of storage. Transformers board derives from Nvidia Ventana development board. This patch brings support for all 3 known T20 Transformers: - Asus Eee Pad Transformer TF101 - Asus Eee Pad Transformer TF101G - Asus Eee Pad Slider SL101 Tested-by: Robert Eckelmann # ASUS TF101 Tested-by: Antoni Aloy Torrens # ASUS TF101 Signed-off-by: Svyatoslav Ryhel --- arch/arm/dts/Makefile | 6 +- arch/arm/dts/tegra20-asus-sl101.dts | 9 + arch/arm/dts/tegra20-asus-tf101.dts | 9 + arch/arm/dts/tegra20-asus-tf101g.dts | 9 + arch/arm/dts/tegra20-asus-transformer.dtsi | 545 ++++++++++++++++++ arch/arm/mach-tegra/tegra20/Kconfig | 5 + board/asus/transformer-t20/Kconfig | 12 + board/asus/transformer-t20/MAINTAINERS | 8 + board/asus/transformer-t20/Makefile | 9 + .../asus/transformer-t20/configs/sl101.config | 1 + .../asus/transformer-t20/configs/tf101.config | 1 + .../transformer-t20/configs/tf101g.config | 1 + board/asus/transformer-t20/transformer-t20.c | 57 ++ configs/transformer_t20_defconfig | 82 +++ doc/board/asus/index.rst | 1 + doc/board/asus/transformer_t20.rst | 129 +++++ include/configs/transformer-t20.h | 21 + 17 files changed, 904 insertions(+), 1 deletion(-) create mode 100644 arch/arm/dts/tegra20-asus-sl101.dts create mode 100644 arch/arm/dts/tegra20-asus-tf101.dts create mode 100644 arch/arm/dts/tegra20-asus-tf101g.dts create mode 100644 arch/arm/dts/tegra20-asus-transformer.dtsi create mode 100644 board/asus/transformer-t20/Kconfig create mode 100644 board/asus/transformer-t20/MAINTAINERS create mode 100644 board/asus/transformer-t20/Makefile create mode 100644 board/asus/transformer-t20/configs/sl101.config create mode 100644 board/asus/transformer-t20/configs/tf101.config create mode 100644 board/asus/transformer-t20/configs/tf101g.config create mode 100644 board/asus/transformer-t20/transformer-t20.c create mode 100644 configs/transformer_t20_defconfig create mode 100644 doc/board/asus/transformer_t20.rst create mode 100644 include/configs/transformer-t20.h diff --git a/arch/arm/dts/Makefile b/arch/arm/dts/Makefile index 06c234afbe..362b4d3b22 100644 --- a/arch/arm/dts/Makefile +++ b/arch/arm/dts/Makefile @@ -94,7 +94,11 @@ dtb-$(CONFIG_ARCH_S5P4418) += \ dtb-$(CONFIG_ARCH_MESON) += \ meson-a1-ad401.dtb -dtb-$(CONFIG_ARCH_TEGRA) += tegra20-harmony.dtb \ +dtb-$(CONFIG_ARCH_TEGRA) += \ + tegra20-asus-sl101.dtb \ + tegra20-asus-tf101.dtb \ + tegra20-asus-tf101g.dtb \ + tegra20-harmony.dtb \ tegra20-medcom-wide.dtb \ tegra20-paz00.dtb \ tegra20-plutux.dtb \ diff --git a/arch/arm/dts/tegra20-asus-sl101.dts b/arch/arm/dts/tegra20-asus-sl101.dts new file mode 100644 index 0000000000..b4709c3e9a --- /dev/null +++ b/arch/arm/dts/tegra20-asus-sl101.dts @@ -0,0 +1,9 @@ +// SPDX-License-Identifier: GPL-2.0 +/dts-v1/;

Currently +U-Boot supports bootmenu entry fastboot, which allows to write a processed copy +of U-Boot permanently into eMMC. + +While pre-loading U-Boot, hold the ``volume down`` button which will trigger +the bootmenu.

Additionally, if the Volume Down button is pressed while booting, the +device will enter bootmenu. Bootmenu contains entries to mount MicroSD and eMMC +as mass storage, fastboot, reboot, reboot RCM, poweroff, enter U-Boot console +and update bootloader (check the next chapter). + +Flashing ``repart-block.bin`` eliminates vendor restrictions on eMMC and allows +the user to use/partition it in any way the user desires. + +Self Upgrading +-------------- + +Place your ``u-boot-dtb-tegra.bin`` on the first partition of the MicroSD card +and insert it into the tablet. Enter bootmenu, choose update the bootloader +option with the Power button and U-Boot should update itself. Once the process +is completed, U-Boot will ask to press any button to reboot. diff --git a/include/configs/transformer-t20.h b/include/configs/transformer-t20.h new file mode 100644 index 0000000000..ca1e70caa7 --- /dev/null +++ b/include/configs/transformer-t20.h @@ -0,0 +1,21 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +/* + * (C) Copyright 2010,2011 + * NVIDIA Corporation + * + * (C) Copyright 2022 + * Svyatoslav Ryhel + */ + +#ifndef __CONFIG_H +#define __CONFIG_H + +#include "tegra20-common.h" +#include "transformer-common.h" + +/* Board-specific serial config */ +#define CFG_SYS_NS16550_COM1 NV_PA_APB_UARTD_BASE + +#include "tegra-common-post.h" + +#endif /* __CONFIG_H */ -- 2.39.5
