Luke, others,
Has there been any recent progress on the crowd-funding campaign or on other things? I know there's been a little off-list correspondence about Gratipay, which is peripheral to everything else, but for the benefit of anyone following the list (either as a subscriber or reading the archives) an update might be informative.
From what I've seen from following other lists, there's progress on Linux device tree support for various Ingenic JZ-series SoCs, which might have a beneficial impact on any jz4755 card that is produced. My own experiments with the jz4720/30/40 have stalled somewhat for the time being, but I'll get back to them at some point, I imagine.
