Configuration address range determination

Hi,

   I am wondering if there is a way to determine the address range used on the Flash chip for configuration knowing the MCS/PRM files.   I see in the PRM file there is an Addr1 and Addr2 field, but after programming the Flash chip and reading it manually back I see it has written data 24 bytes past the Addr2 address.

  I ask because I am wanting to utilize some of the unused space on the flash chip for hardware number identification and need to know what space isn't used so I can make sure to not overwrite any necessary data.

  For reference, I am using Vivado/SDK 2018.1 and am developing for Kintex and Artix 7 chips.

Thanks.

Tim
