190 Early Platform Devices and Drivers
192 The early platform interfaces provide platform data to platform device
193 drivers early on during the system boot. The code is built on top of the
194 early_param() command line parsing and can be executed very early on.
196 Example: "earlyprintk" class early serial console in 6 steps
198 1. Registering early platform device data
201 early_platform_add_devices(). In the case of early serial console this
203 at this point will later on be matched against early platform drivers.
209 User specified early platform devices will be registered at this point.
210 For the early serial console case the user can specify port on the
216 3. Installing early platform drivers belonging to a certain class
218 The architecture code may optionally force registration of all early
222 driver example since the early serial driver code should be disabled
225 4. Early platform driver registration
231 5. Probing of early platform drivers belonging to a certain class
234 registered early platform devices associated with a certain class with
235 registered early platform drivers. Matched devices will get probed().
236 This step can be executed at any point during the early boot. As soon
239 6. Inside the early platform driver probe()
241 The driver code needs to take special care during early boot, especially
244 it is called at early platform device or at the regular platform device
245 time. The early serial driver performs register_console() at this point.
