    C6X: early boot code · c1a144d7

    Original port to early 2.6 kernel using TI COFF toolchain.
    Brought up to date by Mark Salter <msalter@redhat.com>
    
    This patch provides the early boot code for C6X architecture. There is a
    16 entry vector table which is used to direct reset and interrupt events. The
    vector table entries contain a small amount of code (maximum of 8 opcodes)
    which simply branches to the actual event handling code.
    
    The head.S code simply clears BSS, setups up a few control registers, and calls
    machine_init followed by start_kernel. The machine_init code in setup.c does
    the early flat tree parsing (memory, commandline, etc). At setup_arch time, the
    code does the usual memory setup and minimally scans the devicetree for any
    needed information.
