Jiaxun just made changes to the 2E/2F code just a couple of weeks ago to separate it from other Loongson64 support & clean it up - he also indicated at the same time that he intends to contiue maintaining this code [1]. > Ugly: > Loongson-2E/2F are not compatible with regular MIPS, e.g., ebase, cache > flush method and tlb refill handler. Sadly "quirks" like this aren't solely the domain of Loongson 2E/2F machines, so this isn't an unusual burden. > Linux-5.4.x is a LTS release, I think it is the suitable time to remove > Loongson-2E/2F. I disagree - Jiaxun says he's happy to maintain the platform & has recently been working on it. I'm not going to remove it & deny him that chance. If it does indeed become unmaintained then sure let's drop it, but that doesn't seem to be the case here.
