From fa26c71aaf14c7aa46f02fb85b1ee58b4081d4d3 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Mon, 17 Jun 2013 23:45:29 +0900 Subject: ARM: SAMSUNG: Use local definitions of watchdog registers This patch adds local definitions of required watchdog registers and bitfields to the uncompress header, allowing to remove the dependency on plat/regs-watchdog.h header and the ugly hack to replace virtual with physical addresses. In addition, it fixes reboot on decompression failure feature, due to the mentioned ugly hack not working anymore (the macro being redefined got renamed, without fixing this code).
