This will build U-Boot as a pure 64-bit binary with no SPL. It can be used with a pre-stage boot firmware which has already done 16-bit, 32-bit and 64-bit init.

Perhaps X86_RUN_64BIT_NO_SPL? Bin might hav a better idea.
I considered X64_RUN_64BIT_NO_SPL, X64_RUN_64BIT_PURE and X64_RUN_64BIT_NATIVE. Hi Bin, can you recommend better naming?
