• Following params in sblSlaveCoreInfo_t structure are of type int32_t
  • proc_id,
  • dev_id,
  • clk_id,
  • clk_freq

• In sbl_soc_cfg.h, these params #define for invalid cores are defined as 0xBAD00000
• This results in C++ build failure
  • error: constant expression evaluates to 3134193664 which cannot be narrowed to type 'int32_t' (aka 'int') [-Wc++11-narrowing]

*SBL in many places uses the hardcoding 0xBAD00000 to check for invalids*

To avoid the narrowing issues, SBL lib needs to be fixed properly to avoid use hardcoding in many places
and use an appropriate invalid macro(which can be used everywhere)
