enum workspaceInfo

info of how to use the workspace (at memMap type MMAP_T_WORKSPACE or MMAP_T_RAM)

Enumerator:

STAND_ALONE_WORKSPACE	use memory map MMAP_T_WORKSPACE as our workspace
TOP_OF_RAM_WORKSPACE	use top of RAM as workspace (save / restore original data)
BOTTOM_OF_RAM_WORKSPACE	use bottom of RAM as workspace (save / restore original data)
