Hi, Jiaxun,
Hi Huacai
Thanks for your response.
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.
"Loongson" seems too long in some cases, for DeviceTree Bindings, it
will also delicate with vendor String.
As you can see on Loongson's official website
[http://loongson.cn/product/cpu/3/3A3000.html], "LS3A3000" had been
written on the chip as the model name.
In my opinion, "ls3" is a proper abbreviation of Loongson-3 processors.
But it's fine for me to convert "ls" to "loongson" if all people agree
with this.
Btw: I don't think it's a good idea to bring Loongson-2H PCH support to
mainline, as we can see the vendor code have a lot of dirty hacks that
are totally unacceptable to us.
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.
Our discussion was limited on PRID. However, Early Loongson-3A/B
processors is sharing the same PRID_IMP with Loongson-2E/F.
It may lead to confusion if we're using the same way to express totally
different contents.
Notice me if any one have better idea on how to express loongson2ef
family machines.

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maintainance and became outdated.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.
