Hi,
I've not yet had a chance to bisect this but it appears that Arndale boot has broken for me recently in -next; I'm getting absolutely no serial output at all afther the bootloader hands off to Linux so no useful diagnostics. Is this a known issue?
On next-20131018, bisect points to following commit.
commit 65cd4f6c99c1170bd0114dbd71b978012ea44d28 Author: Stephen Boyd sboyd@codeaurora.org Date: Thu Jul 18 16:21:18 2013 -0700 Subject: arch_timer: Move to generic sched_clock framework
I don't know if this is a fix, but removing armv7-timer DT node brings Arndale back to booting state.
