Yes, I meant upstream in QEMU. If I refer to the doc from google:

'goldfish' is the name of a family of similar virtual hardware platforms, that
mostly differ in the virtual CPU they support. 'goldfish' started as an
ARM-specific platform, but has now been ported to x86 and MIPS virtual CPUs.

Goldfish was based on QEMU 0.8.2, they then moved to ranchu, this time
on a more upstream QEMU but I don't think this is upstream either.
