Reimplement BladeRF radio driver, make it work for 5G

This MR reimplements the BladeRF radio driver such that it is usable for
5G. On the way, we remove unused code, refactor it for readability, and
update configuration.

Tested:

- 40MHz carrier as gNB
- 20MHz carries as gNB

An initial focus was 2x2, but I did not manage to do this yet.
Documentation on the format is here [1] and there is a helper [2]. I
will do this later.

BladeRF documentation
=====================
As of 2018-11-06, the bladeRF support is not fully automatic and requires
some manual settings before use. This documentation is the ultimate source
of information. If something described in this file does not work or does
not correspond to the reality, then contact us so we can fix the problems
and update this documentation.
1. Install bladeRF 2.0 libraries.
As of now, it's better to install from source.
So, do not run: ./build_oai -I -w BLADERF
(That is: do not include '-w BLADERF'.)
Instead, follow the instructions at: https://github.com/Nuand/bladeRF
If you already had some bladeRF software installed using automatic
methods, first remove it by hand ('apt-get purge bladeRF' or something
similar, you can get the list of installed bladeRF packages by running
'dpkg -l|grep -i blade', remove them all).
2. Update the device.
Download the latest FX3 firmware and FPGA images from Nuand's website.
As of writing, this is:
https://github.com/Nuand/bladeRF/wiki
That points to the following pages.
For FX3:
http://www.nuand.com/fx3_images/
For FPGA:
http://www.nuand.com/fpga_images/
Install FX3 firmware:
sudo bladeRF-cli -f bladeRF_fw_latest.img
Install FPGA image (this is for BladeRF x40):
sudo bladeRF-cli -L hostedx40-latest.rbf
Retrieve calibration information:
sudo bladeRF-cli -i
info
That outputs the serial number of your device.
Go to:
https://www.nuand.com/calibration
And enter your serial number.
The website tells you to run something like:
sudo bladeRF-cli -i
flash_init_cal 40 0x9271
Actual values depend on your device and serial number.
3. Calibrate the bladeRF device.
We will work with band 7 on 2.68GHz with a bandwidth of 5 MHz (25 RBs).
Plug the bladeRF device, then run:
sudo bladeRF-cli -i
set frequency tx 2680000000
set frequency rx 2560000000
set gain rx 60
set gain tx 60
set bandwidth 5000000
set samplerate 7680000
cal lms
cal lms
cal lms
cal dc rxtx
cal dc rxtx
cal dc rxtx
4. Tune the RX gain using the enb tracer.
Run the softmodem and the 'enb' tracer. For instructions, see:
https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/T/basic
In the enb window, check the 'input signal'. You should see some blue
signal as seen at:
https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/T/enb
(the 'Time signal power' plot).
The level should be around 30.
If it's not around 30 then edit your configuration file and modify
the value 'max_rxgain' in the section 'RUs'.
The configuration file to use is:
configuration/bladeRF/enb-band7-5mhz.conf
In the configuration file, you also need to set the correct values for:
- tracking_area_code
- plmn_list: mcc, mnc, mnc_length
- mme_ip_address: this is the IP address used by the computer running
the softmodem to connect to the EPC
- NETWORK_INTERFACES: all the ENB*ADDRESS* variables have to point
to the IP address of the EPC machine
5. You're good to go.
You can now connect a UE and pass some traffic. If everything is well
configured you can expect more than 16 Mb/s of throughput in the downlink
using iperf and more than 8 Mb/s in the uplink. Looking at the logs, you
should find lines containing 'PHR 40' and 'CQI 15'. If your values are
lower then your setup may need some adjustments.
6. In case of problems.
If the performance of the softmodem is very bad, you can stop it and
run the calibration again, without setting the parameters (frequencies,
gains, etc.). Just run:
sudo bladeRF-cli -i
cal lms
cal dc rxtx
That may help.
Be sure to use proper radio equipment (duplexer, antennas, clean
environment without interferences).

# BladeRF 2.0 Micro Documentation
[TOC]
## Install BladeRF 2.0 Micro Libraries
You can install the BladeRF library by using `build_oai -I -w BLADERF`, which
will install it from the package manager if the distribution supports it, or
falls back to a build from source otherwise.
If you intentionally want to install BladeRF from source, you can follow
[Nuand's Getting Started
guide](https://github.com/Nuand/bladeRF/wiki/Getting-Started%3A-Linux#building-bladerf-libraries-and-tools-from-source)
to do so.
## Configure the device
### Image Flash
Download the latest FX3 firmware and FPGA images from Nuand's website. There
are [fx3 images](http://www.nuand.com/fx3_images/) and [FPGA
images](http://www.nuand.com/fpga_images/). Download and save the corresponding
files to your computer, then install the FX3 firmware
sudo bladeRF-cli -f bladeRF_fw_latest.img
and install the FPGA image (this is x40):
sudo bladeRF-cli -L hostedx40-latest.rbf
### Use of the configuration file
This configuration will help the bladeRF board to load the bitstream images
automatically, and can be used to set some options automatically that are not
configured by OAI.
Create the bladeRF config file:
```bash
$ cat ~/.config/Nuand/bladeRF/bladerf.conf
# Load the hostedx40.rbf FPGA image, set the trim DAC, and
# configure the frequency
fpga ~/.config/Nuand/bladeRF/image.rbf
# trimdac 592
# frequency 2.4G
```
More information is available at [Nuand's
website](https://nuand.com/libbladeRF-doc/v2.5.0/configfile.html).
### Useful commands for `bladerf-cli`
`bladeRF-cli` can be used to query various device details.
Show the version of bladeRF and device details
bladeRF-cli --exec version
bladeRF-cli --exec info
Probe for a specific device
bladeRF-cli --probe
Print some information on device capabilities and current configuration
(bandwidth, frequency, clocking and sample rate, various features)
bladeRF-cli --exec print
### Calibration
Retrieve calibration serial number:
bladerf-cli --exec info
Go to the [Nuand calibration page](https://www.nuand.com/calibration) and enter
your serial number. The website tells you to run something like:
sudo bladeRF-cli -i
flash_init_cal 40 0x9271
Actual values depend on your device and serial number.
You can also rerun a calibration like so
sudo bladeRF-cli -i
cal lms
cal dc rxtx
## OAI
### Build BladeRF driver
You can use `build_oai` to build with BladeRF support, e.g.,
cd openairinterface5g/cmake_targets/
./build_oai --ninja --nrUE --gNB -w BLADERF
or you can use cmake directly
cd openairinterface5g/
cmake -B build -G Ninja -DOAI_BLADERF=ON
cmake --build build -t oai_bladerfdevif # to build only the driver
cmake --build build # to build it all
For more information about the build, please refer to [the build
documentation](../../doc/BUILD.md).
### Adapt the OAI-gNB configuration file to your system
You can start from a [sample BladeRF configuration
fiel](../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.51PRB.bladerf20xa0.conf).
The only BladeRF-specific configuration resides in `RUs.[0].sdr_addrs`. This
string is passed to
[`bladerf_open()`](https://www.nuand.com/libbladeRF-doc/v2.6.0/group___f_n___i_n_i_t.html#gab341ac98615f393da9158ea59cdb6a24)
and can be used to select a specific BladeRF device. For instance, to open a
specific device with serial 730f5a36545849d9aa71ca6cf50e8ca0 on USB, you would
add `libusb: serial=730f5a36545849d9aa71ca6cf50e8ca0`.
The TX gain is automatically chosen to be the maximum, and can be reduced with
`att_tx`. The RX gain is taken from `RUs.[0].max_rxgain`, and can be attenuated
with `att_rx`.
The rest of the paramaters (PLMN, frequencies, IP addresses) is the same as in
any other configuration. Refer to the [general
tutorials](../..//doc/NR_SA_Tutorial_OAI_CN5G.md) for more information.
### Run the setup
Assuming you built from source above:
cd ~/openairinterface5g/build/
sudo ./nr-softmodem -O ../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.51PRB.bladerf20xa0.conf -E
### In case of problems
Refer back to the calibration section above. If not done yet, consider
calibrating your device.
You can get more logs from BladeRF. To do so, you have to edit the code and
modify this line inside [`bladerf_lib.c`](./bladerf_lib.c).
```patch
- bladerf_log_set_verbosity(BLADERF_LOG_LEVEL_INFO);
+ bladerf_log_set_verbosity(BLADERF_LOG_LEVEL_VERBOSE);
```
in function `device_init()`.
