This add frame DMA functionality to the Sparx5 platform.

Ethernet frames can be extracted or injected autonomously to or from the
device’s DDR3/DDR3L memory and/or PCIe memory space. Linked list data
structures in memory are used for injecting or extracting Ethernet frames.
The FDMA generates interrupts when frame extraction or injection is done
and when the linked lists need updating.
Something to fix:

drivers/net/ethernet/microchip/sparx5/sparx5_fdma.c: In function ‘sparx5_fdma_start’:
drivers/net/ethernet/microchip/sparx5/sparx5_fdma.c:544:6: warning: variable ‘proc_ctrl’ set but
not used [-Wunused-but-set-variable]
  544 |  u32 proc_ctrl;
      |      ^~~~~~~~~
Will do.

Thanks for the review.

BR
Steen
