Yes they use their own custom U-Boot, with a lot of changes and code
duplication, and added x86 emulation to run a VGA BIOS, and never
upstreamed the changes... much like any other vendor, sadly.

I once managed to build a binary from their published source code with
an old compiler, although it's not exactly the same of the binary used,
which I think is actually run with the on-chip RAM or something weird alike.
