[PATCH v3 2/4] fpga: xilinx: reorganize to subdir layout
From: trix@redhat.com
Date: 2021-06-11 16:22:08
Also in:
linux-fpga, lkml
Subsystem:
fpga manager framework, the rest · Maintainers:
Moritz Fischer, Xu Yilun, Linus Torvalds
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
