* xen, rpi4: Fix syntax in linux-yocto bbappendluca fancellu2021-10-082-6/+6
| | | | | | | | | | | | | Syntax conversion for bbappend linux-yocto_5.10 and linux-yocto-dev inside the raspberrypi dynamic layer.

* xen, rpi4, linux-yocto: enable linux-yocto 5.10 for RPi4Christopher Clark2021-04-293-4/+14
| | | | | | | | Added to the raspberrypi dynamic layer for use with Xen as preparation for switching to it as the default preference. Signed-off-by: Christopher Clark <christopher.w.clark@gmail.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
* xen, linux-yocto-dev, RPi4: weaker assign for KBRANCH and KMACHINEChristopher Clark2020-12-281-2/+2
| | | | | | | | | | Switch to use ?= to set KBRANCH_raspberrypi4-64 to make it easier to override elsewhere when needed for switching to a different kernel branch. Also make the same change for KMACHINE_raspberrypi4-64 to match how it is assigned in the meta-yocto-bsp layer.

* xen, raspi4, linux-yocto-dev: Enable Xen on Raspberry Pi 4Christopher Clark2020-08-111-0/+10
| | | | | | | | | | | Enable linux-yocto-dev as the Linux kernel for Xen on the Raspberry Pi 4, with the bcm-2xxx-rpi4 KMACHINE and KBRANCH. Set a Raspberry Pi SD card variable to increase the size of the boot partition to accommodate both the kernel and the Xen hypervisor.

* xen, linux-raspberrypi: add Linux kernel 5.4 patches for Xen supportChristopher Clark2020-07-0611-0/+586
Kernel patches are in process of Linux review and submission, and are backported from the Linux Foundation's Eve Project kernel from 5.6 to 5.4 (some patches not needed for 5.4, hence gaps in the patch sequence number) https://github.com/lf-edge/eve/tree/master/pkg/new-kernel/patches-5.6.x A bbappend applies Xen overrides to the boot command line. Since linux-raspberrypi depends on linux-yocto, and linux-yocto_virtualization introduces a requirement for cfg/virtio.scc obtain it from the yocto kernel cache.
