Ok, good to know, thanks for the background.
The way we came up with the list of unused boards is to assume they are all unused unless someone asked for it to be kept around for this time, for pretty much any reason. I probably forgot to have you on the Cc list when we discussed this in the past.
IIRC, nobody specifically asked about keeping either the corgi or the spitz series, the reason for keeping it was to have at least one handheld platform with qemu support remain for testing, but I don't see a reason for keeping more than one of them.
If you feel like we should keep tosa or corgi and ask again next year, we could do that, but reworking the series to keep tosa around would have additional side-effects on the tmio-mmc driver that can otherwise get cleaned up quite a bit.
In the long run, I expect we will remove all the remaining legacy boardfiles and only keep the DT support. Ideally if someone is motivated to convert spitz to DT, supporting corgi the same way is also easy.
