Hi, Jiaxun, 1, To describe CPU I prefer "loongson" to "ls" because "ls" is confusing, and in future we will use ls2h/ls7a to describe Loongson's bridge. 2, I think it is better to use loongson64c/loongson64g than loongson2ef/loongson64. As we disscussed, we will use PRID_IMP_LOONGSON_64C/PRID_IMP_LOONGSON_64G to describe 0x6300/0xc000.

However, it seems like recent years, they are focusing on maintain a kernel by themselves rather than contribute there code to the community. Kernel is progress rapidly too. Their code slept in mainline for a long peroid without proper maintainance and became outdated. This patchset brings modern DeviceTree and irqchip support to the Loongson64 machine, and leaves Loongson 2e/f alone since they are too legacy to touch.
