The BeagleBone platforms all use a common mechanism to discover and identify extension boards (called "capes"): each extension board has an I2C-connected EEPROM describing itself. This patch implements a generic extension_scan_board() feature that can be used by all BeagleBone platforms to read those I2C EEPROMs and fill in the list of "extension" structures. Following commits will enable this common logic on two BeagleBone platforms. Signed-off-by: Kory Maincent <kory.maincent@bootlin.com>
