The new flash.c file contains the logic to flash a new image on the adapter, through a hcall. It is an iterative process, with chunks of data of 1M at a time. There are also 2 phases: write and verify. The flash operation itself is driven from a user-land tool. Once flashing is successful, an rtas call is made to update the device tree with the new properties values for the adapter and the AFU(s) Add a new char device for the adapter, so that the flash tool can access the card, even if there is no valid AFU on it.
