net: dc2114x: Use dev_remap_addr()

2026-06-03T14:55:55Z

Use dev_remap_addr() to simplify code. dev_remap_addr() does same thing as dev_read_addr() + map_physmem(). And it supports both live device tree and flat DT backends, avoiding direct dependency on devfdt_* helpers. No functional changes. Reviewed-by: Simon Glass Signed-off-by: Peng Fan

net: dc2114x: Include env.h to permit reading the environment

This file uses the environment but does not include the header file. Update it. Signed-off-by: Simon Glass

Merge a patch series to improve dc2114x support

2024-10-27T23:04:02Z

This patch series by Hanyuan Zhao provides a number of improvements to the dc2114x driver. Link: https://lore.kernel.org/r/tencent_BD4B002FC63A5F77969D9BD1FFF125371C08@qq.com

net: dc2114x: remove the pass all multicast flag in operation mode settings

2024-10-27T16:15:29Z

Remove the OMR_PM flag and choose 16 perfect filtering mode since in modern networks there're plenty of multicasts and set ORM_PM flag will increase the dc2114x's workload and ask the U-Boot to handle packets not related to itself. And most of the time, U-Boot does not need this feature. Signed-off-by: Hanyuan Zhao

net: dc2114x: allow users to decide how to tx packets according to IP core

2024-10-27T16:15:29Z

Some IP cores of dc2114x or its variants do not comply so well with the behaviors described by the official document. Originally this driver uses only one tx descriptor and organizes it as a ring buffer, which would lead to a problem that one packet would be sent twice. This commit adds support to prevent this bug if you are using IP cores with this issue, by using multiple tx descriptors and organizing them as a real well-defined ring buffer.

net: dc2114x: allow users to decide whether to detect the tx No Carrier errors

2024-10-27T16:15:29Z

Some IP cores of dc2114x or its variants do not comply so well with the behaviors described by the official document. A packet could be sent successfully but reported with No Carrier error. Latest drivers of this IP core have not detect this error anymore. Signed-off-by: Hanyuan Zhao

net: dc2114x: remove unused lines and change the var and print types

2024-10-27T16:15:29Z

This commit fixes a problem that even though the network card does not report any issues in transmitting a setup frame, the driver prints the error status every time. Let's set it for debug use. Signed-off-by: Hanyuan Zhao

net: dc2114x: add support for CPUs that have cache between the memory and the card

2024-10-27T16:15:29Z

This commit adds support for the MIPS and LoongArch CPUs, which would use cache after they jump into U-Boot. This commit requests the CPU to return the addresses in uncached windows and flushes the cache in need, to make sure the memory between the CPU and the network card is in consistency.

net: dc2114x: set the card number to start at zero

2024-10-27T16:15:29Z

Otherwise the number might get kind of weird. Signed-off-by: Hanyuan Zhao

net: dc2114x: get mac address from environment

2024-10-27T16:15:29Z

Let this old driver work like the other newer network card drivers, loading the MAC address from environment, which could be more flexible to set. Signed-off-by: Hanyuan Zhao
