2018-07-19	d5a23af Browse files » RAS: Introduce handler for Double Faults ... Double fault is when the PE receives another error whilst one is being handled. To detect double fault condition, a per-CPU flag is introduced to track the status of error handling. The flag is checked/modified while temporarily masking external aborts on the PE. This patch routes double faults to a separate platform-defined handler.

2018-07-19	b56dc2a Browse files » RAS: Introduce handler for Uncontainable errors ... Uncontainable errors are the most severe form of errors, which typically mean that the system state can't be trusted any more. This further means that normal error recovery process can't be followed, and an orderly shutdown of the system is often desirable. This patch allows for the platform to define a handler for Uncontainable errors received. Due to the nature of Uncontainable error, the handler is expected to initiate an orderly shutdown of the system, and therefore is not expected to return. A default implementation is added which falls back to platform unhandled exception. Also fix ras_arch.h header guards.

2018-07-17	ee6ff1b Browse files » RAS: Validate stack pointer after error handling ... RAS handling flows might involve using setjmp/longjump calls introduced in earlier patches; therefore, it'd be good to make sure the stack has been unwound completely after the handling. This patch inserts ASM assertions on the RAS handling path to validate stack.

We enlarge it to 11 MB for passing the test. Also we reduce the NS_DRAM0_SIZE from 13MB to 4MB so that the whole section is still fit in 16MB.

	1931d1d Browse files » ARM platforms: Make arm_lock static ... The ARM_INSTANTIATE_LOCK macro defines a lock meant to be further manipulated using the arm_lock_init/get/release() macros. It has 2 variants, depending on the BL image it is compiled for. One version defines the lock variable with internal linkage whereas the other one, with external linkage. Code that uses these macros is not compliant with MISRA rule 8.4 because when using the external linkage version, there is no visible declaration for the lock variable. This patch defines the arm_lock variable with internal linkage in both cases. This fits well the way these macros are used in the code today, where the lock is not used outside of the translation unit it is defined in.
