Soby Mathew	626ed510f1	Rework the crash reporting in BL3-1 to use less stack ... This patch reworks the crash reporting mechanism to further optimise the stack and code size. The reporting makes use of assembly console functions to avoid calling C Runtime to report the CPU state. The crash buffer requirement is reduced to 64 bytes with this implementation. The crash buffer is now part of per-cpu data which makes retrieving the crash buffer trivial. Also now panic() will use crash reporting if invoked from BL3-1. Fixes ARM-software/tf-issues#199 Change-Id: I79d27a4524583d723483165dc40801f45e627da5	2014-07-28 11:03:20 +01:00
Andrew Thoelke	aaba4f2827	Move CPU context pointers into cpu_data ... Moving the context pointers for each CPU into the per-cpu data allows for much more efficient access to the contexts for the current CPU. Change-Id: Id784e210d63cbdcddb44ac1591617ce668dbc29f	2014-06-16 21:34:47 +01:00
Andrew Thoelke	5e91007424	Per-cpu data cache restructuring ... This patch prepares the per-cpu pointer cache for wider use by: * renaming the structure to cpu_data and placing in new header * providing accessors for this CPU, or other CPUs * splitting the initialization of the TPIDR pointer from the initialization of the cpu_data content * moving the crash stack initialization to a crash stack function * setting the TPIDR pointer very early during boot Change-Id: Icef9004ff88f8eb241d48c14be3158087d7e49a3	2014-06-16 21:30:32 +01:00
