    plat/arm/sgi: Use NT_FW_CONFIG instead of HW_CONFIG · 77ab969a
    Chandni Cherukuri authored
    
    With the two new APIs 'plat_arm_sgi_get_platform_id' and
    'plat_arm_sgi_get_config_id' that are available now, BL31 need not
    depend on hw_config device tree to identify the platform. In addition
    to this, the existing hardware description in hw_config can be limited
    to use by BL33 and not by the operating system.
    
    So the hardware description from hw_config dts can be moved into
    nt_fw_config dts and the use of hw_config dts can be removed.
