2020-11-16libpayload/i8042: Increase response timeout to 1.5sNico Huber
The current timeout of 500ms is too low. For instance self-test of the KBC integrated into IT8516E took almost 1s in tests. We already check for presence of the KBC before the self-test. So the timeout should only trigger on a hardware defect and we can leave some margin.

2019-03-02libpayload: i8042: Only test PS/2 AUX port when enabledDuncan Laurie
If a PS/2 AUX device is not present then the AUX test command during i8042_probe() will time out and add ~500ms to the boot time. In order to avoid this only test the PS/2 AUX port if CONFIG_LP_PC_MOUSE is enabled. BUG=b:126633269 TEST=boot on device without AUX port and check that this command does not get executed, saving ~500ms at boot.
