From: Tom Rix <trix@redhat.com>

The incoming xrt patchset has a toplevel subdir xrt/
The current fpga/ uses a single dir with filename prefixes to subdivide owners
For consistency, there should be only one way to organize the fpga/ dir.
Because the subdir model scales better, refactor to use it.
The discussion wrt xrt is here:
https://lore.kernel.org/linux-fpga/68e85a4f-4a10-1ff9-0443-aa565878c855@redhat.com/

Follow drivers/net/ethernet/ which has control configs
NET_VENDOR_BLA that map to drivers/net/ethernet/bla
Since fpgas do not have many vendors, drop the 'VENDOR' and use
FPGA_BLA.

There are several new subdirs
altera/
dfl/
lattice/
xilinx/

Each subdir has a Kconfig that has a new/reused

if FPGA_BLA
  ... existing configs ...
endif FPGA_BLA

Which is sourced into the main fpga/Kconfig

Each subdir has a Makefile whose transversal is controlled in the
fpga/Makefile by

obj-$(CONFIG_FPGA_BLA) += bla/

Some cleanup to arrange thing alphabetically and make fpga/Makefile's
whitespace look more like net/'s

Changes from
v1
  Drop renaming files
  Cleanup makefiles

v2
  Expand commit messages
  Add SPDX to Kconfig
  Expand new Kconfig variable help messages

Follow drivers/net/ethernet/ which has control configs
NET_VENDOR_BLA that map to drivers/net/ethernet/bla
Since fpgas do not have many vendors, drop the 'VENDOR' and use
FPGA_BLA.

There are several new subdirs
altera/
dfl/
lattice/
xilinx/

Each subdir has a Kconfig that has a new/reused

if FPGA_BLA
  ... existing configs ...
endif FPGA_BLA

Which is sourced into the main fpga/Kconfig

Each subdir has a Makefile whose transversal is controlled in the
fpga/Makefile by

obj-$(CONFIG_FPGA_BLA) += bla/

This is the dfl/ subdir part.

Create a dfl/ subdir
Move dfl-* files to it.
Add a Kconfig and Makefile

Because FPGA_DFL is now used in dfl/Kconfig in a if/endif
block, all the other configs in dfl/Kconfig implicitly depend
on FPGA_DFL.  So the explicit dependence can be removed.  Also
since FPGA_DFL depends on HAS_IOMEM, it can be removed from the
other configs.

From: Tom Rix <trix@redhat.com>

Follow drivers/net/ethernet/ which has control configs
NET_VENDOR_BLA that map to drivers/net/ethernet/bla
Since fpgas do not have many vendors, drop the 'VENDOR' and use
FPGA_BLA.

There are several new subdirs
altera/
dfl/
lattice/
xilinx/

Each subdir has a Kconfig that has a new/reused

if FPGA_BLA
  ... existing configs ...
endif FPGA_BLA

Which is sourced into the main fpga/Kconfig

Each subdir has a Makefile whose transversal is controlled in the
fpga/Makefile by

obj-$(CONFIG_FPGA_BLA) += bla/

This is the xilinx/ subdir part

Create a xilinx/ subdir
Move xilinx-* and zynq* files to it.
Add a Kconfig and Makefile

From: Tom Rix <trix@redhat.com>

Follow drivers/net/ethernet/ which has control configs
NET_VENDOR_BLA that map to drivers/net/ethernet/bla
Since fpgas do not have many vendors, drop the 'VENDOR' and use
FPGA_BLA.

There are several new subdirs
altera/
dfl/
lattice/
xilinx/

Each subdir has a Kconfig that has a new/reused

if FPGA_BLA
  ... existing configs ...
endif FPGA_BLA

Which is sourced into the main fpga/Kconfig

Each subdir has a Makefile whose transversal is controlled in the
fpga/Makefile by

obj-$(CONFIG_FPGA_BLA) += bla/

This is the lattice/ subdir part.

Create a lattice/ subdir
Move ice40* and machxo2* files to it.
Add a Kconfig and Makefile

You should update Documentation/fpga/dfl.rst too as it mentions
"drivers/fpga/dfl-fme-pr.c". This update was in your initial patch 5 so
it's lost now, but it really should be in this patch.
