* [PATCH v2 1/5] fpga: generalize updating the card
@ 2021-05-20 18:29 trix

From: trix @ 2021-05-20 18:29 UTC (permalink / raw)
  To: mdf, hao.wu, michal.simek
  Cc: linux-fpga, linux-kernel, linux-arm-kernel, Tom Rix

From: Tom Rix <trix@redhat.com>

There is a need to update the whole card.  An fpga can
contain non-fpga components whose firmware needs to be
updated at the same time as the fpga rtl images and
may need to be handled differently from the existing
fpga reconfiguration in the the fpga manager.

Move the write_* ops out of fpga_manager_ops and
into a new fpga_manager_update_ops struct.  Add
two update_ops back to fpga_manager_ops,
reconfig for the exiting functionality and
reimage for the new functionity.

Rewire fpga devs to use reconfig ops
