The purpose of .work section

[SAeeD]

According to c/src/lib/libbsp/arm/shared/startup/linkcmds.base, it takes
the whole space of RAM:
    RamBase = ORIGIN (REGION_WORK);
    RamSize = LENGTH (REGION_WORK);

Why the whole space?
Why some BSPs like CSB337 don't have .work in their linkcmds? Is it
unnecessary?

Thanks,
SAeeD
