2018-10-12[RCAR] Enable Linux-based hypervisor execution in AGLRonan Le Martret1-0/+5
The upstream version of AGL boots Linux in EL1. This mode is not privileged enough to put in place the correct configuration of an hypervisor (e.g., KVM). This patch leverages the ATF rcar platform configuration variables to boot the Linux kernel in EL2, instead of EL1, allowing Linux-based hypervisors such as KVM to configure all the necessary stubs to properly run virtual machines. This patch has been successfully tested with ATF, KVM and AGL rootfs on the Renesas R-Car M3. Changelog: - Added arm-trusted-firmware patch, which makes this work easy to be tested by the community - This patch version does not contain Linux kernel modifications. In fact, these resulted not necessary with the proposed ATF patch and a recent kernel (higher than 4.6) Bug-AGL: SPEC-497 Bug-AGL: SPEC-1571 Signed-off-by: Michele Paolino <m.paolino@virtualopensystems.com> Signed-off-by: Ronan Le Martret <ronan.lemartret@iot.bzh> Change-Id: I8d20e36a09be1dba35b10193643ea00e4f388e95 Signed-off-by: Ronan Le Martret <ronan.lemartret@iot.bzh>
