Subject: [PATCH 2/8] firmware: google: Init coreboot bus with subsys_initcall()
Date: Thu,  8 Jan 2026 15:19:42 +0100	[thread overview]
Message-ID: <20260108145058.56943-3-tzimmermann@suse.de> (raw)
In-Reply-To: <20260108145058.56943-1-tzimmermann@suse.de>

Using module_init()/device_initcall() is too late to initialize
the coreboot bus, as there might already be drivers that depend
on it.

So far this hasn't been a problem, as coreboot controls all device
creation. Initializing the coreboot bus earlier in subsys_initcall()
will allow for external coreboot drivers to register themselves
with device_initcall(). Prepares coreboot to support additional
coreboot drivers from other subsystems.
