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)

The operation mode of the PMIC for Salvator-X and ULCB are different:
- ULCB : PULSE MODE (PMIC_LEVEL_MODE=0)
- Salvator-X : LEVEL MODE (PMIC_LEVEL_MODE=1(default))
This commit updates arm-trusted-firmware recipe to check
PMIC_LEVEL_MODE option and to control the corresponding PMIC.
