177       early during system boot.
191 The early platform interfaces provide platform data to platform device
192 drivers early on during the system boot. The code is built on top of the
193 early_param() command line parsing and can be executed very early on.
195 Example: "earlyprintk" class early serial console in 6 steps
197 1. Registering early platform device data
200 early_platform_add_devices(). In the case of early serial console this
202 at this point will later on be matched against early platform drivers.
208 User specified early platform devices will be registered at this point.
209 For the early serial console case the user can specify port on the
215 3. Installing early platform drivers belonging to a certain class
217 The architecture code may optionally force registration of all early
221 driver example since the early serial driver code should be disabled
230 5. Probing of early platform drivers belonging to a certain class
233 registered early platform devices associated with a certain class with
234 registered early platform drivers. Matched devices will get probed().
235 This step can be executed at any point during the early boot. As soon
238 6. Inside the early platform driver probe()
240 The driver code needs to take special care during early boot, especially
243 it is called at early platform device or at the regular platform device
244 time. The early serial driver performs register_console() at this point.
