xhfc-breaout: Conncet SPI_INV to GND
...
This was missing from the v1 design. SPI_INV must be tied to either high
or low to select the SPI clock polarity. It was tied to low by manawyrm
in his manual rework, so let's reflect this in the design accordingly.

Add schematics + PCB layout for a simple AMR break-out board
...
AMR (Audio Modem Riser) is a standard for pluggable boards with
audio codecs to connect to the AC97 interface of mainboards dating
to the late-90ies / early 2000s.
The idea of this break-out boards is to be able to interface such a
modem riser card with a microcontroller or FPGA, basically using them
as a digital interface to analog phone lines for softmodem development
as part of osmocom retronetworking.
