This commit gives the secure world access to the I2C bus so it can communicate with I2C slaves (typically those would be secure elements like the NXP SE050). A similar service implementation has been merged in linux: c05210ab ("drivers: optee: allow op-tee to access devices on the i2c bus") Signed-off-by: Jorge Ramirez-Ortiz <jorge@foundries.io> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Etienne Carriere <etienne.carriere@linaro.org>
