-Kobol Helios64
-==============
-
-The `default.nix` module provides the required setup for the system to work.
-
-The `recommended.nix` module adds recommended settings for the system.
-
-Status
-------
-
-### Works
-
- - SATA hard drives
- - Ethernet (1gbps)
- - Serial through USB type-c (`ttyS2`)
-
-### Untested
-
- - Ethernet (2.5gbps)
- - DP video out
- - UPS behaviour
- - `rootfs` on SATA drives
-
-### Disabled
-
-Due to misbehaviour, `ttyS0` (`&uart0`, `serial@ff180000`) has been disabled
-via a kernel patch.
-
-Without this change, using, or attempting to use `ttyS0` will break serial
-output from `ttyS2`.
-
-
-Kernel
-------
-
-Only Linux 5.10 (LTS) is supported, using the patch set derived from Armbian.
-
-
-Requirements
-------------
-
-A *platform firmware* needs to be provided out of band for the system.
-
-The author recommends Tow-Boot, for which a [draft pull request](https://github.com/Tow-Boot/Tow-Boot/pull/54)
-adds support for the Helios64.
-
-Any other supported *platform firmware* should work too.
-
-> **NOTE**: at the time of writing (2021-10-10) the *platform firmware*
-> **must** make use of the proprietary ram training. The open source equivalent
-> will make the system unstable, and worse, will cause silent memory
-> corruption, in addition to loud memory corruption.
-
-
-Notes
------
-
-### Baud rate
-
-The serial baud rate is configured for `115200`, which is a more common default
-than the usual for Rockchip at `1500000`. See [the rationale for the decision](https://github.com/Tow-Boot/Tow-Boot/pull/33).
