    Add support for asynchronous FIQ handling in TSP · 757d5911
    Achin Gupta authored
    This patch adds support in the TSP to handle FIQ interrupts that are
    generated when execution is in the TSP. S-EL1 interrupt are handled
    normally and execution resumes at the instruction where the exception
    was originally taken. S-EL3 interrupts i.e. any interrupt not
    recognized by the TSP are handed to the TSPD. Execution resumes
    normally once such an interrupt has been handled at EL3.
