-== OsmoTRX hardware device support
-
-OsmoTRX consists of a _common_ part that applies to all TRX devices as well as
-_hardware-specific_ parts for each TRX device. The hardware-specific parts are
-usually provided by vendor-specific or device-specific libraries that are then
-handled by some OsmoTRX glue code presenting a unified interface towards the
-rest of the code by means of a _RadioDevice_ class.
-
-The common part includes the core TRX architecture as well as code for
-implementing the external interfaces such as the TRX Manager UDP socket,
-control, and VTY interfaces.
-
-The hardware-specific parts include support for driving one particular
-implementation of a radio modem.  Such a physical layer
-implementation can come in many forms.  Sometimes it runs on a general
-purpose CPU, sometimes on a dedicated ARM core, a dedicated DSP, a
-combination of DSP and FPGA.
-
-Joining the common part with each of the available backends results in a
-different binary with different suffix for each backend. For instance, when
-OsmoTRX is built with UHD backend, an _osmo-trx-uhd_ binary is generated; when
-OsmoTRX is built with LimeSuite backend, an _osmo-trx-lms_ binary is generated.
-Build of different backend can be enabled and disabled by means of configure
-flags, which can be found in each subsection relative to each backend below.
