That's not quite true though, is it?

Please also add riscv,isa-base & riscv,isa-extensions.

You should add () around the GPL-2.0 OR MIT.

huh? So these are random numbers below? Either put something useful here
or delete it please.

Sorry for late reply.

The clint is parsed by sbi. As use the same compatible, the opensbi will
parse the device twice. This will cause a fault.

Sorry for late reply, The clint consists of mtimer and ipi devices, which
is defined in [1]. This standard shows clint(or the aclint) has two device,
but not one. In another word, there is no need to defined mtimer and ipi
device on the same base address. So we need two compatibles to allow sbi
to identify them correctly.

The cpu cores of SG2042 is c902 from T-HEAD, it supports vector, but
it's v0.7, not official v1.0. If we declare it as supporting
v-extension, the latest kernel(since 6.5) will issue rvv1.0
instructions during booting and make c902 crash. So we have to remove
"v" from the capability of ISA to pass the booting of machine. You can
check the "riscv,isa = "rv64imafdc";" in DTS.

I just cited a description from TRM of SG2042 and it looks too long. I
will give a better description here and avoid using "......" in the
next revision.

It should be unnecessary， I will remove it in the next revision.

The memory for SG2042 is not fixed, the bootloader will detect memory
installed on board during booting and fill the actual address and size
in the memory node. The comment " /* the mem node will be updated by
ZSBL. */" is telling this.
We write memory nodes like this to make them act just as placeholders
and the value is by default written as zero.

I know all of this, not my first rodeo looking at stuff using T-Head
cores ;)
What I meant was, imafdc is only a subset of what is supported,
there are other things like the T-Head bitmanip extensions too, right?
I'm not asking for it to be listed in the devicetree (yet), just
actually curious what else is on the c920 as I do not speak a language
that allows me to read the documentation for the cpu that I have been
able to find online.

Yes, I read the comment!

Why knowingly add something that is wrong, rather than omitting them
entirely?

We learn this from arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dts,
it writes DTS as following:

```
memory@0 {
device_type = "memory";
/* rewrite this at bootloader */
reg = <0x0 0x0 0x0 0x0>;
};
```
So you mean we can totally remove the memory nodes in DTS and make
bootloader add it by itself? That sounds a good idea, I will have a
try. I used to think memory nodes are must-have in DTS.
