Broadcom I2C controller driver. Follwoing API's are supported:- - i2c_init() Intialize ethe I2C controller - i2c_probe() - i2c_set_bus_speed() Set the I2C bus speed - i2c_get_bus_speed() Get the current bus speed - i2c_recv_byte() Receive one byte of data. - i2c_send_byte() Send one byteof data - i2c_read_byte() Read single byte of data - i2c_read() Read multiple bytes of data - i2c_write_byte Write single byte of data - i2c_write() Write multiple bytes of data This driver is verified by reading the DDR SPD data.

Trusted Firmware-A
Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.
TF-A implements Arm interface standards, including:
- Power State Coordination Interface (PSCI)
- Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)
- SMC Calling Convention
- System Control and Management Interface (SCMI)
- Software Delegated Exception Interface (SDEI)
The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.
In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.
Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
