[U-Boot] single build of uboot supporting env stored in dynamically detected boot device
by Tim Harvey 22 Apr '15

22 Apr '15

Greetings, It seems the U-Boot's env storage is implemented by various types of storage from common/env_*.c, one (and only one) which is included by common/Makefile based off of the CONFIG_ENV_IS_IN_* config. I want to build a single uboot image which can be installed on one of several supported boot devices (NAND, SATA, SD for example) and have the env storage hooked to the device that was detected as the boot device. Am I correct in assuming this is not currently possible and that instead I would have to build 3 versions of uboot each with one type of storage defined? If it turns out that this is not currently possible, I'm open to suggestions on how to rectify it (or if you think I'm crazy for wanting to have a single uboot image for the above please explain your reasoning). I'm thinking I would start by making the env_init/saveenv functions (I believe those are the only ones that need to be implemented by an env storage subsystem) unique function names, then creating a wrapper for those functions that call the right one. Regards, Tim

[U-Boot] [PATCH v3] mx6: Add initial SPL support for HummingBoard-i2eX
by Fabio Estevam 22 Apr '15

22 Apr '15

From: Fabio Estevam <fabio.estevam(a)freescale.com> Add the initial SPL support for HummingBoard-i2eX, which is based on a MX6 Dual. For more information about HummingBoard, please check: http://www.solid-run.com/products/hummingboard/ Based on the work from Jon Nettleton and Rabeeh Khoury. Signed-off-by: Fabio Estevam <fabio.estevam(a)freescale.com> --- Currently only HummingBoard-i2eX is supported. After this initial patch is accepted, then we can add the other Hummingboard and Cubox-i variants as well. Changes since v2: - Avoid undef CONFIG_CMD_IMLS as suggested by Tom - Change the name from mx6cuboxi_spl_defconfig to mx6cuboxi_defconfig as spl will be the only supported method for these boards Changes since v1: - Addressed several comments made by Tom Rini - Remove empty lines from README as pointed out by Nikolay Dimitrov - Fixed sparse warnings - Fixed DDR settings arch/arm/Kconfig | 6 + board/solidrun/mx6cuboxi/Kconfig | 15 ++ board/solidrun/mx6cuboxi/MAINTAINERS | 6 + board/solidrun/mx6cuboxi/Makefile | 9 + board/solidrun/mx6cuboxi/README | 21 +++ board/solidrun/mx6cuboxi/mx6cuboxi.c | 330 +++++++++++++++++++++++++++++++++++ configs/mx6cuboxi_defconfig | 6 + include/configs/mx6cuboxi.h | 205 ++++++++++++++++++++++ 8 files changed, 598 insertions(+) create mode 100644 board/solidrun/mx6cuboxi/Kconfig create mode 100644 board/solidrun/mx6cuboxi/MAINTAINERS create mode 100644 board/solidrun/mx6cuboxi/Makefile create mode 100644 board/solidrun/mx6cuboxi/README create mode 100644 board/solidrun/mx6cuboxi/mx6cuboxi.c create mode 100644 configs/mx6cuboxi_defconfig create mode 100644 include/configs/mx6cuboxi.h diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 7ed0e20..7c383cb 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -523,6 +523,11 @@ config TARGET_MX6SABRESD select CPU_V7 select SUPPORT_SPL +config TARGET_MX6CUBOXI + bool "Support Solid-run mx6 boards" + select CPU_V7 + select SUPPORT_SPL + config TARGET_MX6SLEVK bool "Support mx6slevk" select CPU_V7 @@ -856,6 +861,7 @@ source "board/siemens/draco/Kconfig" source "board/siemens/pxm2/Kconfig" source "board/siemens/rut/Kconfig" source "board/silica/pengwyn/Kconfig" +source "board/solidrun/mx6cuboxi/Kconfig" source "board/solidrun/hummingboard/Kconfig" source "board/spear/spear300/Kconfig" source "board/spear/spear310/Kconfig" diff --git a/board/solidrun/mx6cuboxi/Kconfig b/board/solidrun/mx6cuboxi/Kconfig new file mode 100644 index 0000000..31d88b2 --- /dev/null +++ b/board/solidrun/mx6cuboxi/Kconfig @@ -0,0 +1,15 @@ +if TARGET_MX6CUBOXI + +config SYS_BOARD + default "mx6cuboxi" + +config SYS_VENDOR + default "solidrun" + +config SYS_SOC + default "mx6" + +config SYS_CONFIG_NAME + default "mx6cuboxi" + +endif diff --git a/board/solidrun/mx6cuboxi/MAINTAINERS b/board/solidrun/mx6cuboxi/MAINTAINERS new file mode 100644 index 0000000..3d468ed --- /dev/null +++ b/board/solidrun/mx6cuboxi/MAINTAINERS @@ -0,0 +1,6 @@ +MX6CUBOXI BOARD +M: Fabio Estevam <fabio.estevam(a)freescale.com> +S: Maintained +F: board/solidrun/mx6cuboxi/ +F: include/configs/mx6cuboxi.h +F: configs/mx6cuboxi_spl_defconfig diff --git a/board/solidrun/mx6cuboxi/Makefile b/board/solidrun/mx6cuboxi/Makefile new file mode 100644 index 0000000..df425ac --- /dev/null +++ b/board/solidrun/mx6cuboxi/Makefile @@ -0,0 +1,9 @@ +# +# Copyright (C) 2007, Guennadi Liakhovetski <lg(a)denx.de> +# +# (C) Copyright 2011 Freescale Semiconductor, Inc. +# +# SPDX-License-Identifier: GPL-2.0+ +# + +obj-y := mx6cuboxi.o diff --git a/board/solidrun/mx6cuboxi/README b/board/solidrun/mx6cuboxi/README new file mode 100644 index 0000000..3050c48 --- /dev/null +++ b/board/solidrun/mx6cuboxi/README @@ -0,0 +1,21 @@ +How to use U-boot on Solid-run mx6 hummingboard +----------------------------------------------- + +- Build U-boot for hummingboard: + +$ make mrproper +$ make mx6cuboxi_defconfig +$ make + +This will generate the SPL image called SPL and the u-boot.img. + +- Flash the SPL image into the SD card: + +sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1;

[U-Boot] [PATCH 3/3 v2] arm: mx6: tqma6: Extract baseboard configs into separate config file
by Stefan Roese 22 Apr '15

22 Apr '15

This patch extracts all baseboard specific defines into a separate config file. This makes it easier to add other baseboards that use the TQMa6 SoM. This patch will be used by the upcoming WRU-IV board support which also uses the TQMa6 SoM.

[U-Boot] [PATCH] arm: mx6: ddr: add pd_fast_exit flag to system information
by Tim Harvey 22 Apr '15

22 Apr '15

DDR3 has a special Precharge power-down mode: fast-exit vs slow-exit. In slow-exit mode the DLL is off but in some quiescent state that makes it easy to turn on again in tXPDLL cycles (about 10tCK) vs the full tDLLK (512tCK). In fast-exist mode the DLL is maintained such that it is ready again in about 3tCK.
