+# Docker images for CI
+
+Each directory contains the files for a docker image.
+
+## Building an image
+
+When building a docker image, the build context is expected to be where this
+`README.md` file resides. This means that building the images will require
+passing the appropriate `-f` argument.
+
+Here is an example for building the `dco-check` image:
+
+```
+docker build --no-cache . -f dco-check/Dockerfile -t dco-check
+```

+This image provides the environment and the logic of running a DCO check
+against a repository.
+
+## Configuration
+
+The `entrypoint.sh` script assumes at runtime that the repository to be checked
+is available under `/work`. This path is to be populated via bind mounts when

+In order to use CAN with an MCP2515-based module, set the following variables:
 
-	ENABLE_SPI_BUS = "1"
-	ENABLE_CAN = "1"
+    ENABLE_SPI_BUS = "1"
+    ENABLE_CAN = "1"
 
-See: <http://skpang.co.uk/catalog/pican2-canbus-board-for-raspberry-pi-23-p-1475.html>
+In case of dual CAN module (e.g. PiCAN2 Duo), set following variables instead:
+
+    ENABLE_SPI_BUS = "1"
+    ENABLE_DUAL_CAN = "1"
+
+Some modules may require setting the frequency of the crystal oscillator used on the particular board. The frequency is usually marked on the package of the crystal. By default, it is set to 16 MHz. To change that to 8 MHz, the following variable also has to be set:
+
+    CAN_OSCILLATOR="8000000"
+
+Configure the interrupt pin to the one connected to the CAN module. By default,
+the pins are set to 25 for can0 and 24 for can1. To change them to 12 and 16,
+the following variables also have to be set:
+
+    CAN0_INTERRUPT_PIN = "12"
+    CAN1_INTERRUPT_PIN = "16"

+## Enable infrared
+
+Users who want to enable infrared support, for example for using LIRC (Linux
+Infrared Remote Control), have to explicitly set in local.conf:
+
+    ENABLE_IR = "1"
+
+This will add device tree overlays gpio-ir and gpio-ir-tx to config.txt.
+Appropriate kernel modules will be also included in the image. By default the
+GPIO pin for gpio-ir is set to 18 and the pin for gpio-ir-tx is 17. Both pins
+can be easily changed by modifying variables `GPIO_IR` and `GPIO_IR_TX`.
+
+## Enable gpio-shutdown
+
+When using device tree kernels, set this variable to enable gpio-shutdown:
+
+    ENABLE_GPIO_SHUTDOWN = "1"
+
+This will add the corresponding device tree overlay to config.txt and include
+the gpio-keys kernel module in the image. If System V init is used, additional
+mapping is applied to bind the button event to shutdown command. Systemd init
+should handle the event out of the box.
+
+By default the feature uses gpio pin 3 (except RPi 1 Model B rev 1 enumerates
+the pin as gpio 1). This conflicts with the I2C bus. If you set `ENABLE_I2C`
+to `1` or enabled `PiTFT` support, or otherwise want to use another pin, use
+`GPIO_SHUTDOWN_PIN` to assign another pin. Example using gpio pin 25:
+
+     GPIO_SHUTDOWN_PIN = "25"

+RaspberryPi does not have the unicam device ( RaspberryPi Camera ) enabled by default.

+## WM8960 soundcard support
+
+Support for WM8960 based sound cards such as the WM8960 Hi-Fi Sound Card HAT for Raspberry Pi from Waveshare, and ReSpeaker 2 / 4 / 6 Mics Pi HAT from Seeed Studio, can be enabled in `local.conf`
+
+    ```conf
+    MACHINE_FEATURES += "wm8960"
+    ```
+
+You may need to adjust volume and toggle switches that are off by default
+
+    ```bash
+    amixer -c1 sset 'Headphone',0 80%,80%
+    amixer -c1 sset 'Speaker',0 80%,80%
+    amixer -c1 sset 'Left Input Mixer Boost' toggle
+    amixer -c1 sset 'Left Output Mixer PCM' toggle
+    amixer -c1 sset 'Right Input Mixer Boost' toggle
+    amixer -c1 sset 'Right Output Mixer PCM' toggle
+    ```
+
+Audio capture on ReSpeaker 2 / 4 / 6 Mics Pi HAT from Seeed Studio is very noisy.
+
+## Support for RTC devices
+
+The RaspberryPi boards don't feature an RTC module and the machine
+configurations provided in this BSP layer have this assumption (until, if at
+all, some later boards will come with one).
+
+`rtc` is handled as a `MACHINE_FEATURES` in the context of the build system
+which means that if an attached device is provided for which support is needed,
+the recommended way forward is to write a new machine configuration based on an
+existing one. Check the documentation for
+`MACHINE_FEATURES_BACKFILL_CONSIDERED` for how this is disabled for the
+relevant machines.
+
+Even when `MACHINE_FEATURES` is tweaked to include the needed `rtc` string,
+make sure that your kernel configuration is supporting the attached device and
+the device tree is properly tweaked. Also, mind the runtime components that
+take advantage of your RTC device. You can do that by checking what is
+included/configured in the build system based on the inclusion of `rtc` in
+`MACHINE_FEATURES`.

+From: Mauro Salvini <m.salvini@koansoftware.com>

+Subject: [PATCH] rpi: always set fdt_addr with firmware-provided FDT address
+Date: Wed, 12 May 2021 14:39:45 +0200	[thread overview]
+Message-ID: <20210512123945.25649-1-m.salvini@koansoftware.com> (raw)
+
+Raspberry firmware prepares the FDT blob in memory at an address
+that depends on both the memory size and the blob size [1].
+After commit ade243a211d6 ("rpi: passthrough of the firmware provided FDT
+blob") this FDT is passed to kernel through fdt_addr environment variable,
+handled in set_fdt_addr() function in board file.
+
+When u-boot environment is persistently saved, if a change happens
+in loaded FDT (e.g. for a new overlay applied), firmware produces a FDT
+address different from the saved one, but u-boot still use the saved
+one because set_fdt_addr() function does not overwrite the fdt_addr
+variable. So, for example, if there is a script that uses fdt commands for
+e.g. manipulate the bootargs, boot hangs with error
+
+libfdt fdt_check_header(): FDT_ERR_BADMAGIC
+
+Removing the fdt_addr variable in saved environment allows to boot.
+
+With this patch set_fdt_addr() function always overwrite fdt_addr value.
