xen, rpi4: add xen-rpi-u-boot-scr recipe for default u-boot script

2021-04-30T03:05:11+00:00

Add a new xen-rpi-u-boot-scr recipe to PROVIDE u-boot-default-script instead of using a bbappend to rpi-u-boot-scr. This allows the new recipe to be selected by indicating it as PREFERRED_PROVIDER of u-boot-default-script, and then do that in the Xen on Raspberry Pi 4 config file, xen-raspberrypi4-64.inc.

xen, rpi4: move rpi4-machine+xen-distro cfg into dynamic layer

2021-04-30T03:05:11+00:00

Improve meta-virt-xen.inc by moving all the Raspberry Pi 4 config settings to a new xen-raspberrypi4-64.inc file in the raspberrypi dynamic layer. The new .inc file is included only for the raspberrypi4-64 MACHINE, so the config settings no longer need to be applied using overrides.

xen, rpi4: apply workaround to fix crash on boot with Xen 4.14

2021-04-30T03:05:11+00:00

Apply update to the device tree to allow Xen 4.14 to boot. Suggested-by: Bertrand Marquis Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield

xen, rpi4: fix u-boot script to load binaries from boot partition

2021-04-30T03:05:11+00:00

fatload needs to read from mmc 1:1 to find the Xen hypervisor and Linux kernel binaries with the current Yocto Linux 5.10 kernel. Add boot messages to to the u-boot script to indicate the size of files loaded for easier confirmation of load success. Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield

xen, rpi4, linux-yocto: enable linux-yocto 5.10 for RPi4

2021-04-30T03:05:11+00:00

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 Signed-off-by: Bruce Ashfield

xen, rpi4: drop the raspberrypi4-64 defconfig, xen_git.bbappend

2021-04-30T03:05:11+00:00

Since upstream Xen 4.14 and 4.15 have working default configs for Xen on the Raspberry Pi 4, the defconfig and bbappend in the raspberrypi dynamic layer can now be removed. Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield

xen, rpi4: use the preferred generic multiboot,module compatible string

2021-04-30T03:05:11+00:00

This string has been preferred since 2014 -- ref: Xen commit a860dfeec and also current documentation: docs/misc/arm/device-tree/booting.txt Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield

xen, linux-yocto-dev, RPi4: weaker assign for KBRANCH and KMACHINE

2020-12-29T03:54:16+00:00

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. Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield

xen, raspi4, linux-yocto-dev: Enable Xen on Raspberry Pi 4

2020-08-11T19:58:37+00:00

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. Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield

xen, linux-raspberrypi4: remove linux-raspberrypi bbappends and patches

2020-08-11T19:58:37+00:00

Retiring use of the downstream vendor kernel for use with Xen. Signed-off-by: Christopher Clark Signed-off-by: Bruce Ashfield
