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, rpi4: use RPI_EXTRA_CONFIG and drop the rpi-config_git.bbappend2020-08-11T19:58:37+00:00Christopher Clarkchristopher.w.clark@gmail.com2020-08-07T07:05:01+00:00urn:sha1:738bd333a9d3d39b12643efd1f1afe60d0e3080d
The GIC that is needed by Xen can be enabled via the rpi-config recipe
variable. Fixes the build after the upstream recipe changed recently.

Replaces the prior use of earlyprintk which is an x86-specific option.

xen, linux-raspberrypi: add Linux kernel 5.4 patches for Xen support2020-07-06T20:25:56+00:00Christopher Clarkchristopher.w.clark@gmail.com2020-06-30T01:54:51+00:00urn:sha1:abed1be72d4ddac02087e9e549f70ecf3a9a0322
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.

xen, raspberry pi: add dynamic-layer for Xen configuration for Rpi42020-07-06T20:25:56+00:00Christopher Clarkchristopher.w.clark@gmail.com2020-06-30T01:54:49+00:00urn:sha1:90a01fcbd93d2efc94ca5d296e6a5d45fa9778ec
A Xen-specific u-boot script is needed for launching Xen, and the GIC
(interrupt controller) needs to be enabled.
Since this is both Xen-specific and Raspberry Pi-specific, use a
dynamic layer to conditionally enable the recipes when both
meta-virtualization and meta-raspberrypi are in use together.
