Some sensors connected to Unisoc mailbox will send data very frequently. This makes channel 0 very busy and the messages from other remote cores not able to be handled as soon as possible. It's a trick (un-documented) from Unisoc ASIC designers to resolve this special requirement that an inbox assigned to one of the remote cores before was modified to be exposed to host cpu core. Then from host side, a supplementary inbox is added for transferring mass but not emergency messages from the remote cores, such as step counting sensor, with an independent FIFO and interrupt which is as same as channel 0. Meanwihle, inbox part of this channel is still kept for original remote core to use.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
