* tree: Port programmers to pass programmer_cfg to extractorsEdward O'Callaghan2022-09-071-3/+3
| | | | | | | | | | | | | | | | | | | | | Ran; ``` $ find -name '*.c' -exec sed -i 's/extract_programmer_param_str(NULL/extract_programmer_param_str(cfg/g' '{}' \; ``` Manually fix i2c_helper_linux.c and other cases after. Treat cases of; - pcidev.c , and - usb_device.c as exceptional to be dealt with in later patches.

* tree: Change signature of extract_programmer_param_str()Edward O'Callaghan2022-09-071-2/+2
| | | | | | | | | | | | | | | | | Results can be reproduced with the following invocation; ``` $ find -name '*.c' -exec sed -i 's/extract_programmer_param_str(/extract_programmer_param_str(NULL, /g' '{}' \; ``` This allows for a pointer to the actual programmer parameters to be passed instead of a global.

* Add `str` extension to extract_programmer_param function nameChinmay Lonkar2022-07-021-2/+2
| | | | | | | | | | | | | This patch changes the function name of extract_programmer_param() to extract_programmer_param_str() as this function name will clearly specify that it returns the value of the given parameter as a string.

* lspcon_i2c_spi: Extract I2C bus parameter handlingAngel Pons2021-05-091-0/+47
| | | | | | | | | | | | Introduce the `i2c_open_from_programmer_params` function to avoid having to duplicate parameter parsing code on all I2C programmers. This also allows having the same programmer parameters on all I2C programmers.

* lspcon_i2c_spi: support a devpath optionPeter Marheine2021-05-021-17/+21
| | | | | | | | | | | | | | | | | | | | | | Some callers may find it easier to provide the path to an I2C device at which to communicate with the device, rather than specify the bus number- doing so might involve trying to parse a path to extract the number only for flashrom to do the reverse, which is error-prone and unnecessary. This change adds support for a `devpath` option, continuing to allow `bus` and requiring only one of them be specified. TEST=Verified --flash-size outputs correct values with both devpath=/dev/i2c-7 and bus=7, as well as noting that one is required if neither is specified and only one may be specified if both are given.

* i2c_helper_linux.c: Use a fixed-size bufferAngel Pons2021-04-181-20/+9
| | | | | | | | | | | | | Given that the buffer size is known in advance, using malloc() is not necessary. To avoid open-coding buffer sizes, add some trailing null characters to `I2C_DEV_PREFIX`, as placeholders for bus number digits. Finally, replace the now-unnecessary `goto` statements with `return`.
