161 early during system boot.
175 The early platform interfaces provide platform data to platform device
176 drivers early on during the system boot. The code is built on top of the
177 early_param() command line parsing and can be executed very early on.
179 Example: "earlyprintk" class early serial console in 6 steps
181 1. Registering early platform device data
184 early_platform_add_devices(). In the case of early serial console this
186 at this point will later on be matched against early platform drivers.
192 User specified early platform devices will be registered at this point.
193 For the early serial console case the user can specify port on the
199 3. Installing early platform drivers belonging to a certain class
201 The architecture code may optionally force registration of all early
205 driver example since the early serial driver code should be disabled
214 5. Probing of early platform drivers belonging to a certain class
217 registered early platform devices associated with a certain class with
218 registered early platform drivers. Matched devices will get probed().
219 This step can be executed at any point during the early boot. As soon
222 6. Inside the early platform driver probe()
224 The driver code needs to take special care during early boot, especially
227 it is called at early platform device or at the regular platform device
228 time. The early serial driver performs register_console() at this point.
