From 7f6ae79280eabce22f1df3c858617c6e890e3594 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Thu, 20 May 2021 22:47:02 -0700 Subject: device: Consider fw_config probing in `is_dev_enabled()` With the introduction of fw_config support in coreboot, it is possible for mainboards to control the state of a device (on/off) in ramstage using fw_config probe conditions. However, the device tree in immutable in all other stages and hence `is_dev_enabled()` does not really reflect the true state as in ramstage. This change adds a call to `fw_config_probe_dev()` in `is_dev_enabled()` when device tree is immutable (by checking DEVTREE_EARLY) to first check if device is disabled because of device probe conditions. If so, then it reports device as being disabled. Else, dev->enabled is used to report the device state. This allows early stages (bootblock, romstage) to use `is_dev_enabled()` to get the true state of the device by taking probe conditions into account and eliminates the need for each caller to perform their own separate probing.
