Does U-Boot support booting an Intel 64bit Linux kernel?
Yes, in various ways. See for example x86-fit-boot.txt (and README.x86).
The bootloader itself doesn't need to be 64bit, but it needs (for me) to boot a 64bit kernel with the full memory address space available.
U-Boot normally runs in 32-bit mode on x86. There is experimental 64-bit x86 support (see chromebook_link64), but it is not ready for use, unless you want to improve it :-)
What about UEFI?
Yes, it supports booting as a UEFI payload. It also can run an an EFI app (really just for debugging). It can also run EFI apps. See README.efi
