Component Name

Platform/SoC Supported

Bug Description

Yocto

  • MicroBlaze

  • Zynq-7000

  • Zynq UltraScale+ MPSoC

  • Zynq UltraScale+ RFSoC

  • Versal

All:

  • Added support for U-boot user specified dts by setting below variables in local.conf file:
    UBOOT_USER_SPECIFIED_DTS:pn-u-boot-xlnx = "versal-vck190-revA-x-ebm-01-revA"
    This will fetch user specified dts from from u-boot repo path u-boot-xlnx/arch/arm/dts/versal-vck190-revA-x-ebm-01-revA.dts when user doesn't want to use EXT_DTB from device-tree recipes.

Versal:

  • extract-cdo: Avoid directly populating ${DEPLOY_DIR_IMAGE}

    • This created problems when images are deployed from sstate cache.  

      • Issue can be avoided by extracting the xilinx-bootbin boot.bin file into the extract-cdo build dir ${B} and deployed from the output from ${B}

    • Commit adjusted to change extraction directory vs copying the boot.bin

    • Updated the summary to better reflect what this is doing, as well as the do_compile comment

    • Disabled (noexec) the do_install as this is not a target package

Zynq-7000:

  • meta-xilinx: Clean up vendor specific machine configuration files

    • Add new metal-xilinx-vendor layer which supports vendor specific machine configuration files, device-tree, kernel, platform-init etc.

  • Moved below vendor machine conf files, dt and related configs from meta-xilinx-bsp and meta-xilinx-contrib to meta-xilinx-vendor layer.

    • microzed-zynq7.conf

    • minized-zynq7.conf

    • picozed-zynq7.conf

    • zedboard-zynq7.conf

    • zybo-zynq7.conf

    • zybo-linux-bd-zynq7.conf

    • ultra96-zynqmp.conf

  • Obsoleted qemu-zynq7, s3adsp1800-qemu-microblazeeb, v350-versal and vc-p-a2197-00-versal from meta-xilinx-bsp layer

    • Users should use zynq-generic.conf for zynq7000. qemu boot should be functionally equivalent to qemu-zynq7

  • Added new MAINTAINERS.md file and move maintainers

  • Updated README.md file for supported board machines files in meta-xilinx-bsp, meta-xilinx-contrib and meta-xilinx-vendor layers

  • Disabled old drm kernel patches for zybo-linux-bd-zynq mahcine in meta-xilinx-contrib layer as these patches doesn't apply on 5.x
    kernel, if we don't hear from patch submitter we will remove these patches from meta-xilinx-contrib layer.

  • Removed drm kernel cache metadata for zybo-linux-bd-zynq7 machine as these configs are already available in xilinx_zynq_defconfig.

  • Fixed build issue for u-boot by changing PREFERRED_PROVIDER_virtual/bootloader from u-boot to u-boot-xlnx.

  • Added meta-xilinx-vendor to bblayers.conf.sample
