[U-Boot] FOSDEM 2019 Hardware Enablement Devroom Call for Participation
by Paul Kocialkowski 03 Nov '18

03 Nov '18

Hi, The Hardware Enablement devroom is back for a second year at FOSDEM! It will take place on Sunday 3 February 2019. # Call for Participation We are opening the call for participation to our devroom, with the deadline for talk proposals set to Saturday 1 December 2018. # Devroom Scope This devroom covers topics related to hardware support and enablement with free software. It includes the following topics: * peripheral/controller firmwares * boot software * kernel drivers and hardware interfaces * hardware-related adaptation in operating systems * tools for firmware flashing * tools for low-level development Despite this large scope, the focus of the devroom is set on highlighting the technical aspects of the hardware and its enablement in free projects, rather than the specific applications and use cases that benefit from it. We also want to avoid purely commercial vague talks with marketing content, which leave little place to technical aspects. This year, we are looking to particularly highlighting free software outside of the operating system boundaries, especially with boot software as well as controller and peripheral firmwares. # Talk Format Since no Embedded devroom is taking place this year (and our devroom also covers embedded devices), we are expecting a significant number of submissions. In order to cover as much ground as we can, a new talk will be scheduled every half-hour, so accepted talks will follow this format: 20 minutes for the talk + 5 minutes for questions + 5 minutes for speaker setup We ask speakers to be present in the room before their talk so that speaker setup can go smoothly. # Submission Talks that fit in our devroom's scope can be submitted to the FOSDEM Pentabarf interface at https://penta.fosdem.org/submission/FOSDEM19 We encourage reusing accounts from previous years instead of creating new ones: * lost password: https://penta.fosdem.org/user/forgot_password * new Account: https://penta.fosdem.org/user/new_account/FOSDEM19 Here are a few guidelines when submitting a talk: * select the Hardware Enablement devroom as track * include an abstract for every submission and optionally a full description * make sure your contact details are up to date # Video Talks will be streamed live during the event and recorded. They will be available under a Creative Commons Attribution (BY) license later. # Contact For more information or questions about the devroom and this CFP, feel free to email hardware-devroom-manager at fosdem.org We're looking forward to lots of interesting proposals and hoping to see you all in Brussels at the event! Cheers, Paul for the Hardware Enablement devroom

[U-Boot] Feedback: Device probe during boot
by Vabhav Sharma 03 Nov '18

03 Nov '18

Hello Maintainer/Owners, Please provide your valuable input Referring '[PATCH] drivers: serial: probe all serial devices' email regarding unified way to probe device during boot using DM model I would like to take this thread forward and request your time to help identify the design framework 1. In dm_init(), * Identify the class of devices to be probed * Call dm_set_uclass_autoprobe(enum uclass_id, bool) 2. In core file on every device class * uclass_next_device() to iterate through next device There would be config option to choose probe all devices or not Let me know your time if I can schedule skype session for further discussion NOTE: Attaching previous threads discussed on this issue Regards, Vabhav

[U-Boot] [RFC PATCH v3 0/3] python tools to inspect configs
by Jean-Jacques Hiblot 03 Nov '18

03 Nov '18

This series introduce 2 new python tools that helps getting an overview of the configuration options. First one is fairly simple and is used to locate deconfigs based on several criteria: 'arch', 'soc', 'cpu', 'vendor', 'board', 'defconfig name', 'maintainer' and 'status'. All the parameters use regexp. ex: Show all defconfigs of platforms built around imx25 or imx27 or imxs $ tools/find_defconfigs.py --soc 'mx(25|27|s)' The 2nd tool is used to produce a CSV file that summarizes the usage of config options by a set of defconfigs. Useful to check what platforms might need modifications when working on a particular option. ex: Get the TI platforms that enable CONFIG_DM_I2C_COMPAT either in u-boot or the SPL $ tools/configs2csv.py -X CONFIG_DM_I2C_COMPAT --spl --u-boot --vendor ti \ --discard-empty limitations: - must be executed at the root of the source tree - the source tree must be clean (make mrproper) - only supports CSV format. visualization in terminal sould be added. But LibreOffice calc is better suited with all its ordering/ filtering capabilities. Changes in v3: - Add more comments to describe the classes and functions - Stylistics changes Changes in v2: - basically rewrote the whole thing - use tools/moveconfig.py to generate the database of configs - use tools/find_defconfigs.py to get the list of defconfigs off interest - removed diff with .config. tools/moveconfig.py does a better job Jean-Jacques Hiblot (3): tools: moveconfig: Add an option to build a fuller database of options tools: Add a tool to get a list of defconfigs based on filters tools: Add a tool to get an overview of the usage of CONFIG options tools/configs2csv.py | 427 +++++++++++++++++++++++++++++++++++++++++++++++ tools/find_defconfigs.py | 204 ++++++++++++++++++++++ tools/moveconfig.py | 56 ++++++- 3 files changed, 680 insertions(+), 7 deletions(-) create mode 100755 tools/configs2csv.py create mode 100755 tools/find_defconfigs.py -- 2.7.4

[U-Boot] [PATCH 0/3] MIPS: fix building and linking of standalone programs
by Daniel Schwierzeck 02 Nov '18

02 Nov '18

This series fixes the long-time broken support of standalone programs on MIPS. All MIPS standalone programs now use the main MIPS linker script and all available code size optimizations. Finally the deprecated Makefiles arch/mips/cpu/mips[32,64]/config.mk could be removed. The series also improves the passing of additional linker flags to standalone programs by introducing a Makefile variable LDFLAGS_STANDALONE. Currently the variable CONFIG_STANDALONE_LOAD_ADDR is misused on some archs to pass the path to the linker script. The variable LDFLAGS_STANDALONE now provides a cleaner way to do that. Furthermore it is now possible to migrate CONFIG_STANDALONE_LOAD_ADDR to Kconfig as a hex symbol.

[U-Boot] [PATCH] arm: socfpga: check total size of SPL
by Simon Goldschmidt 02 Nov '18

02 Nov '18

Correctly define CONFIG_SPL_MAX_FOOTPRINT to make the default arm linker script for SPL check the total SRAM size available for SPL (code, data, bss, heap, global data). The previously existing define CONFIG_SPL_MAX_SIZE seems to only check the binary size (which is without bss, heap and gd).
