Something I forgot to mention: I wrote a bit of third-party documentation based on the various vendor kernel trees and it's available at: https://github.com/neuschaefer/wpcm450/wiki Best regards, Jonathan Neuschäfer
Hi Jonathan, Thanks a lot for trying to add WPCM450. Hoever WPCM450 is in EOL for several years and we are not supporting this product anymore. As you said it is only available in the secondary market. Due to it is better not to add the WPCM450 under Nuvoton maintenance. Again we highly appreciate your support and time on NPCM750 patches. have a great weekend Tomer On Sat, 20 Mar 2021 at 20:17, Jonathan Neuschäfer <j.neuschaefer@gmx.net> wrote: > This series adds basic support for the Nuvoton WPCM450 BMC SoC.

I understand. I will instead add a new, separate section for WPCM450 to the MAINTAINERS file. > Again we highly appreciate your support and time on NPCM750 patches. I expect there will be some more cooperation, because the SoCs share some architectural similarity, for example the 100Mbit Ethernet controller. Best regards, Jonathan
