Initial support for Mesa LIMA drivers.
libmali is available but default is set to lima for Yocto Project distributions (without using meta-petalinux layer).
To enable libmali, set config variable in local.conf
Code Block DISTRO_FEATURES:append:aarch64 = " libmali"
New tool called gen-machinceconf which accepts xsa as input and generates yocto bsp machine configuration file. Refer gen-machine-conf repo README for more details.
Instruction for creating a machine configuration file has been updated, Refer to https://github.com/Xilinx/meta-xilinx/blob/master/meta-xilinx-core/conf/machine/README
New docs directory for additional documentation, Refer https://github.com/Xilinx/meta-xilinx/docs
Renamed u-boot-zynq-scr recipe to u-boot-xlnx-scr
The default wic/wks file is provided in meta-xilinx/meta-xilinx-core/wic/xilinx-default-sd.wks
The default file uses ‘rootfs’, instead of ‘bootimg-partition’ for the /boot partition. This allows target package upgrade. ‘bootimg-partition’ is still supported.
The default file also uses --label boot. This ensures the constructed fstab will mount the correct partition(s).
Move AIE recipes from meta-xilinx-tools to meta-xilinx-core layer.
Known Issues and Limitations in Langdale (4.1.2)

gvim binaries doesn't generate when you compile vim recipe with X11 distro features - https://bugzilla.yoctoproject.org/show_bug.cgi?id=15044

Using TCLIBC = "musl" in Yocto causes build failures - This is currently being investigated.
libMali doesn’t work with Weston 10.0, Refer AR 000035056
External media (USB keys) are auto-mounted with permissions which make them unavailable to the default petalinux user - users will need to su/sudo to root in order to access files on these devices.
When building an image using the MACHINE=smk-smk-k{v,r} machine configurations in Yocto for Kria, the resulting images do not contain the correct device-tree - users are advised to use the shared machine configuration MACHINE=k26-smk which will result in an image that can be booted on either the KV or KR board.
