Subject: [PATCH Xilinx Alveo libfdt prep 1/1] Export subset of libfdt symbols for use by other drivers.
Date: Sat, 28 Nov 2020 15:56:59 -0800 [thread overview]
Message-ID: <20201128235659.24679-2-sonals@xilinx.com> (raw)
In-Reply-To: <20201128235659.24679-1-sonals@xilinx.com>
From: Sonal Santan <sonal.santan@xilinx.com>
Some drivers may want to use device tree as metadata format to discover HW
subsystems behind PCIe BAR. This is particularly useful for PCIe FPGA
devices.
