2014-02-20Add exception vector guardsJeenu Viswambharan
This patch adds guards so that an exception vector exceeding 32 instructions will generate a compile-time error. This keeps the exception handlers in check from spilling over. Change-Id: I7aa56dd0071a333664e2814c656d3896032046fe
2014-02-17Setup VBAR_EL3 incrementallyAchin Gupta
This patch ensures that VBAR_EL3 points to the simple stack-less 'early_exceptions' when the C runtime stack is not correctly setup to use the more complex 'runtime_exceptions'. It is initialised to 'runtime_exceptions' once this is done. This patch also moves all exception vectors into a '.vectors' section and modifies linker scripts to place all such sections together. This will minimize space wastage from alignment restrictions. Change-Id: I8c3e596ea3412c8bd582af9e8d622bb1cb2e049d
2014-02-17Fix spilled-over BL1 exception vectorJeenu Viswambharan
The SynchronousExceptionA64 vector has gone beyond the 32-instruction limit for individual exception vector. This patch splits and relocates the exception handler so that it fits into the 32-instruction window. Change-Id: Ic60c4fc3f09a1cb071d63ff0e58353ecaecbb62f
2014-01-20remove empty definition of display_boot_progress()Achin Gupta
This patch replaces the empty definition of display_boot_progress() in bl2_main.c with a weak definition. The former allowed bl2 to use the early_exceptions(). It is possible to do that with a simple weak definition as well. Change-Id: Idb3f425a5e265f3579b638e3d26bd8c9bb78f80d
