[PATCH v5 0/3] Move qfw to DM, add Arm support
by Asherah Connor 07 Mar '21

07 Mar '21

This series moves the QFW driver into a uclass, UCLASS_QFW, and splits the driver into qfw_pio and qfw_mmio. Each driver is selected on the appropriate QEMU board. A sandbox driver is also added, and a DM unit test against that driver. The qfw command is tested in QEMU, and documentation added. Version 5 reworks the series into three patches: 1. Do the DM conversion of existing QFW on x86 2. Add MMIO driver 3. Add the MMIO driver to qemu-arm To view the changes online, see: https://git.src.kameliya.ee/~kameliya/u-boot/log/qfw-priv Changes in v5: * Split conversion of existing x86-only QFW to DM into its own patch. * Split MMIO driver into its own commit. * Split adding MMIO driver to QEMU arm/64 into own commit.

U-Boot CI error, unable to reproduce locally
by Marek Behun 07 Mar '21

07 Mar '21

Hello Tom, I seem to run into an error on Azure's CI for U-Boot that I cannot reproduce locally. It concerns my LTO work https://github.com/u-boot/u-boot/pull/57 The test u-boot.u-boot (test.py xilinx_zynq_virt) is failing with this log https://dev.azure.com/u-boot/a1096300-2999-4ec4-a21a-4c22075e3771/_apis/bui… The error seems to be make[3]: *** read jobs pipe: No such file or directory. Stop. lto-wrapper: fatal error: make returned 2 exit status as if make's jobserver died, or something. But when I build with buildman on my local machine, everything is OK. How should I proceed?

request for i.MX8MM Venice test
by Marek Behun 07 Mar '21

07 Mar '21

Hello Tim, you are listed as maintainer of i.MX8MM Venice board in U-Boot. I am currently working on LTO support for U-Boot, and I have encountered a problem with i.MX8MM Venice board: when LTO is enabled, the linking process for SPL does not throw away relocation information, making the resulting SPL image too big for that board. I have added a patch that discards symbols from .rela* section to my patch series, but I would like you to test whether the patch series works for your board and does not break anything. Could you please clone https://github.com/elkablo/u-boot branch lto, build for imx8mm_venice_defconfig and test whether it boots on your board and maybe test some U-Boot commands (disk reads, kernel booting, ...)? If it does not work, could you also please check with current U-Boot master, to see if it got broken with my patches or with something different? Thank you. Marek

[PATCH] armv8: SPL: discard relocation information
by Marek Behún 07 Mar '21

07 Mar '21

For some reason when building SPL for ARMv8 with LTO, the relocation information is not discarded. Discard it explicitly in the linker script. This fixes LTO build for imx8mm_venice_defconfig.

[PATCH 00/19] video: sunxi: Rework DE2 driver
by Jernej Skrabec 06 Mar '21

06 Mar '21

This series greatly reworks DE2 mixer and accompanying DW-HDMI platform driver. Main goal was to use as many information from device tree as possible and thus removing SoC speficic ifdefs from the code. This was largely accomplished for mixer driver and mostly for HDMI driver. Most of these changes are not user visible. Only improvements relevant to the user are filtering HDMI modes based on pixel clock and searching for additional detailed timings in EDID extension block. This change allows me to use 4k monitor that I have - base EDID block on this monitor holds only 4k@60 detailed timing. Other detailed timings, which are appropriate for HDMI 1.4 controller, are contained in extension block. There is plenty of work to do. TCON handling should go to dedicated driver and clock related code in TCON and DW-HDMI code should be moved to clock drivers. Testing was done only on H3.

Implementation - HABv4 on imx8m
by Suniel Mahesh 06 Mar '21

06 Mar '21

Hi All, We are trying to implement HABv4 on an IMX8M Mini based target. I have followed this discussion[1] and the patch[2]. [1] http://u-boot.10912.n7.nabble.com/Habv4-on-imx8m-tt437232.html#none [2] https://patchwork.ozlabs.org/project/uboot/patch/20210304111742.2369738-1-f… Here are my queries: a. IMX8M Mini doesnt support AHAB, it only supports HABv4. Is my understanding correct ? b. Can you guys point me to any working source repo where HABv4 is tested on imx8m (Fabio talks about the vendor U-Boot code does like this, is this repo accessible ?) c. if (a) is not available, then after applying patch[2], should we need to add/change these two configs for IMX8M Mini: CONFIG_IMX_CONTAINER_CFG CONFIG_SYS_EXTRA_OPTIONS (reference: board/freescale/imx8qm_mek) d. doc/imx/habv4 talks with reference to imx6,7. Are there any other items I need to take care of when working on IMX8M Mini secure boot: Please suggest how should we go about. Thanks and Regards -- Suniel Mahesh Embedded Linux and Kernel Engineer Amarula Solutions India
