Shubha,
You can run the dmem command from the UEFI shell with no parameters, and it
will show the UFI System Table address along with other standard table
addresses.

For a debugger, a platform can produce the EFI_DEBUG_IMAGE_INFO_TABLE. UEFI
Specification Section 17.4.2 describes how a debugger can find the UEFI System
Table address from a structure that is on a 4MB boundary with a signature and a
CRC. This table also provides the list of LOADED_IMAGE_PROTOCOLs for PE/COFF
images that have been loaded, so a debugger can load symbols.
