But the day Allwinner changes its name to Noloser, we'll have a similar problem. Thnk about Freescale vs. NXP, or Altera bought by Intel. No naming scheme is totally future-proof. If the accepted standard through the kernel is to use sunxi to refer to Allwinner SoCs, I don't think it's a bit idea to go with that. > See for instance, TI.
