**PCIe support**
### PCIe (un-)supported
Some H6 SoC based boards (like Pine H64 Model a, discontinued) are shipped with a PCIe slot. This slot can and will not be support by Armbian as it has to be considered as broken by design. [Linux-Sunxi](https://linux-sunxi.org/H6#Errata) writes about this:

> Allwinner H6 has a quirky PCIe controller that doesn't map the PCIe address space properly (only 64k accessible at one time) to CPU, and accessing the PCIe config space, I/O space or memory space will need to be wrapped. As Linux doesn't wrap PCIe memory space access, it's not possible to do a proper PCIe controller driver for H6. The BSP kernel modifies the driver to wrap the access, so it's also not generic, and only devices with modified driver will work.
