DISCLAIMER
==========
Files and directories are gathered from several sources aound the net, mainly
found from the Telegram "Mainline Linux for D1" and "Sipeed" channels.
Everything here is freely available, but sometime protected against bot
download, due to bw limitation, and/or on slow speed lines, making things
harder to download. I believe I can deliver fast mirror, I hope this mirror will
facilatate work of AllWinner D1 and D1s/F133 developers and help the adoption
of this SoC, and more generally RISC-V based SoCs.

D1s or F133-A is a low cost variant of D1
