*	efi_loader: Add runtime services	Alexander Graf	2016-03-15	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	After booting has finished, EFI allows firmware to still interact with the OS using the "runtime services". These callbacks live in a separate address space, since they are available long after U-Boot has been overwritten by the OS. This patch adds enough framework for arbitrary code inside of U-Boot to become a runtime service with the right section attributes set. For now, we don't make use of it yet though. We could maybe in the future map U-boot environment variables to EFI variables here.

*	efi_loader: Add boot time services	Alexander Graf	2016-03-15	1	-0/+781
	When an EFI application runs, it has access to a few descriptor and callback tables to instruct the EFI compliant firmware to do things for it. The bulk of those interfaces are "boot time services". They handle all object management, and memory allocation. This patch adds support for the boot time services and also exposes a system table, which is the point of entry descriptor table for EFI payloads.
