emul: Create an emulation implementation Create a header file and implementation for emulators. Set up a linker list so that emulators can be found and initialised at start-up. Emulators are used to emulate hardware devices, to support testing of various subsystems. For example, it is possible to write an emulator for an I2C compass such that it appears on the I2C bus and can be used just like a real hardware device. Emulators often implement special features for testing. For example a compass may support returning bogus data if the I2C bus speed is too high, or may return invalid measurements if calibration has not yet been completed. This allows for testing that high-level code can handle these situations correctly. Test coverage can therefore approach 100% if all failure conditions are emulated.

emul: Add an emulator for the Atmel AT24 series This emulator supports basic reads and writes with 8-bit addressing. It connects itself to any AT24 devices it finds in the device tree. The I2C emulation controller driver is used to direct I2C messages from the AT24 driver to the AT24 emulator.

emul: Add an emulator for the Bosch BMI160 accelerometer This emulator supports enable functionality to start up the device and read a few samples. It connects itself to any BMI160 device it finds in the device tree. The SPI emulation controller driver is used to direct SPI messages from the BMI160 driver to the BMI160 emulator. Add a few more definitions to the header file, as needed. Signed-off-by: Simon Glass <sjg@chromium.org> 2020-09-19 06:33:09 +08:00			`add_subdirectory(spi)`
