This series allows U-Boot to be built as an EFI payload so that U-Boot can be started on almost any x86 platform that supports EFI. This is implemented as a stub which EFI can load plus a payload that is copied to RAM. The payload contains a normal U-Boot binary image and device tree.
This allows U-Boot to run on platforms that have EFI support but are not supported natively by U-Boot. It also allows testing and fiddling with the board using U-Boots memory display and other commands. In addition, U-Boot can be built as an EFI application. This should work regardless of the board type since it only relies on EFI services. However only 32-bit EFI is supported in this case. Again it can be used to snoop around the platform. A README provides further details of how this series operates.
