* CBI: Allow board to compose data from other sourcesDaisuke Nojiri2019-04-191-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the source of CBI data is only EEPROM. This patch allows CBI data to be composed from other sources such as ADC or some chip register. cbi_board_override is called by CBI library when data is being requested. Boards can implement this callback to add additional bits or bytes to the data. A board itself may need to get CBI data first to manipulate data properly. For such a case, a board can return EC_ERROR_BUSY to inform the callers that the data is not fully ready while a board itself can accept EC_ERROR_BUSY as an expected value.

* cbi: Add a new API for cbi_set_stringFurquan Shaikh2019-03-081-0/+16
| | | | | | | | | | | | | | | | | | | | This change introduces cbi_set_string that can be used by callers to add string data to CBI. Internally, this function ensures that the data is not NULL and call cbi_set_data for the string with a size of strlen + 1. It is added so that callers don't have to repeat the same operations for string data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, field sizes are automatically set to the smallest size which can fit a given value.
