* xen, rpi4: add xen-rpi-u-boot-scr recipe for default u-boot scriptChristopher Clark2021-04-292-72/+0
| | | | | | | | | | | | 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: fix u-boot script to load binaries from boot partitionChristopher Clark2021-04-291-2/+5
| | | | | | | | | | | 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.

* xen, raspberry pi: add dynamic-layer for Xen configuration for Rpi4Christopher Clark2020-07-062-0/+66
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.
