[PATCH 0/5] drivers/net: add NXP FEC-UIO driver

From: Apeksha Gupta
Date: Wed Nov 10 2021 - 00:48:46 EST


This patch series introduce the fec-uio driver, supported for the inbuilt
NIC found in the NXP i.MX 8M Mini SoC. Basic hardware initialization is
performed in kernel via userspace input/output(UIO) to support FEC
ethernet device detection in user space.

Userspace PMD uses standard UIO interface to access kernel for PHY
initialisation and for mapping the allocated memory of register &
buffer descriptor with DPDK which gives access to non-cacheable memory
for buffer descriptor.

Module fec-uio.ko will get generated.
imx8mm-evk-dpdk.dtb is required to support fec-uio driver.
