Subject: [PATCH 0/3] serial, MIPS: Add MIPS UHI semihosting support

Hi all,

This patchset adds support for MIPS UHI semihosting.
It has been implemented on many debugers such as MIPS CodeScape debugger
and OpenOCD.

It is also supported by QEMU's -semihosting option.

I didn't add MAINTAINERS entry for this driver because I find other
simple earlycon drivers don't have one either. Do let me know if it
should be added.

Thanks
Jiaxun
