Subject: [PATCH 0/7] fpga: reorganize to subdirs
From: Tom Rix <trix@...hat.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/
For many of the moved files, they had a prefix bla-* that matched their
new subdir dir name bla/. Those filename are overspecified. So they
were simplified by removing the 'bla-' prefix. If they were *.h files
their guards were also changed.
Some cleanup to arrange thing alphabetically and make fpga/Makefile's
whitespace look more like net/'s
