Hi,
I am trying to use bootelf to load a 64-bit elf binary, but it appears to fail.
I tried using the hello_world from U-Boot sources as well. My U-Boot is based
2015.01 and I have patches applied for 64elf support, and compiled as a 64 bit
U-Boot. Any idea what is need to support bootelf for 64-bit?

elf: Add a very simple ELF64 loader
This adds a very simple ELF64 loader via program headers, similar
to load_elf_image_phdr() that we already have.
