From 726d32bf79ef4042004535c9af9c8ea543abe46f Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Mon, 15 Sep 2014 18:15:55 +0200 Subject: ARM: at91: SAMA5D4 SoC detection code and low level routines SoC identification code, kernel uncompress and low level debugging routines update. On SAMA5D4, DBGU is at another address AT91_BASE_DBGU2 so another round of detection is needed. We also had to differentiate with SAMA5D3 SoC family and rename some variables.
