Andy Ross 928d31125f arch/x86: Add zefi, an EFI stub/packer/wrappper/loader ... This is a first cut on a tool that will convert a built Zephyr ELF file into an EFI applciation suitable for launching directly from the firmware of a UEFI-capable device, without the need for an external bootloader. It works by including the Zephyr sections into the EFI binary as blobs, then copying them into place on startup. Currently, it is not integrated in the build. Right now you have to build an image for your target (up_squared has been tested) and then pass the resulting zephyr.elf file as an argument to the arch/x86/zefi/zefi.py script. It will produce a "zephyr.efi" file in the current directory. This involved a little surgery in x86_64 to copy over some setup that was previously being done in 32 bit mode to a new EFI entry point. There is no support for 32 bit UEFI targets for toolchain reasons. See the README for more details. Signed-off-by: Andy Ross <andrew.j.ross@intel.com>		2020-07-02 09:10:01 -04:00
