Add DTB boot support, only support LS2K1000 processor for now,
determine whether to use the built-in DTB or the DTB from the
firmware by checking the range of CKSEG0 and XKPHYS.loongson_fw
_interface will be used in the future.

Add IO interrupt controller support for Loongson 2k1000, different
from the 3a series is that 2K1000 has 64 interrupt sources, 0-31
correspond to the device tree liointc0 device node, and the other
correspond to liointc1 node.

Use the formal name (Loongson-2K1000, Loongson-3A series), please.

Hi, Huacai
Thank you very much for your reply.
I will modify the submission information,
Use the formal name (Loongson-2K1000, Loongson-3A series) in v4,
Before that, I will wait for other people's opinions about this series.
Thanks,
Qing

So if of_property_match_string() returns an error, you feed that error
to of_iomap()? Somehow, I don't think that's a good idea.

Hi, Marc
Thank you for your suggestion, error handling is missing here,
+ if (index <0)
+ return NULL;
return of_iomap(node, index);
It has been fixed in the fourth version, and I will send V4 soon.

In addition, write assignments on a single line
for (i = 0; i <LIOINTC_NUM_CORES; i++)
priv->core_isr[i] =
liointc_get_reg_byname(node, core_reg_names[i]);
It is 92 characters, more than 80 characters...

Soalready fixed it in v4:).

I really don't care about whatever arbitrary limit people think there
is. Please put it on a single line.
