From fccc2b3675371e4077d7aa7f23d116e97dcdcd07 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 18 Feb 2016 14:21:54 +0100 Subject: soc: versatile: dynamically detect RealView HBI numbers We cannot pile all numbers on this list, just print the three hex digits representing the board ID so we can handle all the new RealView boards.
