Hi there Christian, I did make a post a good while ago to gauge interest (there was none). It is here: https://forum.openwrt.org/t/mx60w-any-interest-in-a-diy-nas-guide-need-some-advice-for-sata-pads-and-msata-slot-compatibility/65718
I have actually tried kmod-ata-ahci out, but with a potentially less-suitable ASM1061. Sadly, once the kmod-ata-ahci module has been kmodloaded, the drives will `ata\d.00: failed to IDENTIFY` -- I ascribed this to an issue with PCIe init on the platform as you described on the linuxppc-dev mailing list, though I had not properly poked the device tree to inform the device of this change. The ASM1061 chipset is known-working on other platforms using OpenWrt (I used two ASM1061s in an Aerohive AP330 as my NAS for a while). I can't seem to find Buckminster / MX60 anywhere in Chris's copy of Meraki's u-boot sources (from https://github.com/riptidewave93/meraki-uboot/). Given the easy JTAG access, recompiling would be the first thing I'd like to try. Otherwise, I suppose I'll try later with a Marvell chipset. Thank you for the reply.
