The problem with H3 (and all other better socs) is t= he lack of a proper SATA controller. A real controller is only available in= A10/A20 SoCs, all others go through a horrible SATA-to-USB adapter that is= horribly slow. > > Anyway, in case we decide to switch, I can keep the A20 running -CURRENT.= I might need some help getting started since I do not have a lot of experi= ence in the kernel, other than the AHCI driver for the imx. Hi Rogiel, FWIW- I'm going to go ahead and write the ccung bits for A10/A20 so that I can make use of my Lamobo R1 when the switch driver for that is finished. This is probably not a bad time to pare down the DTS+U-Boot we build for these SoC to what people are actually willing to claim they use with FreeBSD, though. Thanks, Kyle Evans
