From 1c3ea103d28760a04e457678bf60725ae761c28f Mon Sep 17 00:00:00 2001 From: Antonio Nino Diaz Date: Mon, 1 Feb 2016 13:57:25 +0000 Subject: Remove all non-configurable dead loops Added a new platform porting function plat_panic_handler, to allow platforms to handle unexpected error situations. It must be implemented in assembly as it may be called before the C environment is initialized. A default implementation is provided, which simply spins. Corrected all dead loops in generic code to call this function instead. This includes the dead loop that occurs at the end of the call to panic(). All unnecesary wfis from bl32/tsp/aarch64/tsp_exceptions.S have been removed.
