mainlining shenanigans
54439d20c0
This patch is for enabling cache in SCP. There is not enough space on the SRAM of SCP. We need to run programs in DRAM. The DRAM power and latency is much larger than SRAM, so cache is used to mitigate the negative effects for performance. We set SCP registers for cache size before loading SCP FW. (8KB+8KB) and also adjust ipi_buf_offset in SRAM from 0x7bdb0 to 0x3bdb0 for enabling cache.

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.
