2020-08-18meta-agl-jailhouse: Add support for RPi4 with 2G/4G/8G of memoryjellyfish_9.99.3jellyfish/9.99.39.99.3Jakub Luzny4-2/+96
The Jailhouse configuration files had to be modified to append the additional memory regions present on the higher mem variants of the RPi4. To avoid the use of mem= kernel parameter to fix the memory that can be used by the root cell, a device tree overlay with reserved-memory nodes is used instead. To avoid conflict with the GPU memory, the memory region used for Jailhouse and the non-root cells was moved from 0x30000000 to 0x20000000.

2020-07-24Add layer to support Jailhouse hypervisorjellyfish_9.99.2jellyfish/9.99.29.99.2Jakub Luzny5-0/+56
Jailhouse is a partitioning hypervisor based on Linux. It is able to run bare-metal applications or (adapted) operating systems besides Linux. For this purpose, it configures CPU and device virtualization features of the hardware platform in a way that none of these domains, called "cells" here, can interfere with each other in an unacceptable way. This layer adds the Jailhouse package into AGL and also appends the BSPs to allow it to run. Currently, Raspberry Pi 4 and QEMU x86-64 targets are supported. To enable Jailhouse and include it in the image, the AGL feature agl-jailhouse must be enabled.
