commit 74f9b75f5130765eb713324542cc2ace4015fe9d
Author: Omair Javaid <oma...@li...>

    Configs for ARM corelink SSE-200 target and Musca A board
    
    This patch adds configuration files for ARM CoreLink SSE-200 SoCs. Also
    adds configuration file for SSE-200 based Musca A board. Flash programming
    support for Musca A QSPI flash is still not functional. This configuration
    will be updated once that support lands into OpenOCD.
    
    Please refer to ARM documentation for more information about SSE-200 and
    Musca A.
