valid value greater than 1, the platform code performs required configuration
to support multi-chip operation.
- ``CSS_SGI_PLATFORM_VARIANT``: Selects the variant of a SGI/RD platform. A
particular SGI/RD platform may have multiple variants which may differ in
core count, cluster count or other peripherals. This build option is used
to select the appropriate platform variant for the build. The range of
valid values is platform specific.
