This series fixes a number of issues that exist in the QEMU/mach-virt port of u-boot, and that prevent it from executing correctly under virtualization (as opposed to TCG emulation)
As the Linux EFI subsystem maintainer, I am looking to increase test coverage for the EFI related changes that are under development for Linux, and one of the things I plan to do is start using U-boot as test firmware for boot testing. This can be done under TCG emulation, but given how loosely TCG implements the architecture, it is better to test under virtualization as well.
With these changes applied, u-boot can boot Linux in EFI mode under KVM.
