It would be really nice to have Raspberry Pi-like developer board with this chip. At one point Qualcomm released full documentation for their SoCs, with a publicly available manual with near complete register documentation. I think it was for the APQ8064. It even included Adreno GPU registers and some GPS/WiFi baseband related stuff.
* An unfused SoC, so no secure boot etc. The Efuse VPP pin is tied to ground so no possibility of bricking it by blowing the fuses inadvertently.
* Fully open bootloader, e.g. U-Boot based.
* Mostly complete register documentation for the SoC, that would be good enough.
* Mainline Linux support.
Such a board would take the open source world by storm.
