From 69872e93d971e72cd43fdf90befaaffd8e32437a Mon Sep 17 00:00:00 2001 From: Sekhar Nori Date: Thu, 1 Oct 2009 12:41:06 +0530 Subject: davinci: make it easier to identify SoC init failures This patch makes it easier to identify SoC init failures by panicing when SoC init fails. Without successful SoC init, the kernel eventually fails when attempt is made to access the clocks. Also, an error is printed when JTAG ID match fails to make it easier to identify failures due to SoC rev changes.
