[PATCH v3 0/4] fpga: reorganize to subdirs

trix
2021-06-11T16:21:48Z

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
