Description: write only
- Writing 1 will issue a PERST to card which may cause the card
- to reload the FPGA depending on load_image_on_perst.
+ Writing 1 will issue a PERST to card provided there are no
+ contexts active on any one of the card AFUs. This may cause
+ the card to reload the FPGA depending on load_image_on_perst.
+ Writing -1 will do a force PERST irrespective of any active
+ contexts on the card AFUs.
