In lockstep mode following is TCM address map: | *TCM* | *R5 View* | *Linux view* | | R5_0 ATCM (128 KB) | 0x0000_0000 | 0xFFE0_0000 | | R5_0 BTCM (128 KB) | 0x0002_0000 | 0xFFE2_0000 | Current driver keeps single TCM carveout in lockstep mode as ATCM and BTCM addresses form contiguous memory region. Although the addresses are contiguous, it is not same type of memory. ATCM typically holds interrupt or exception code that must be accessed at high speed. BTCM typically holds a block of data for intensive processing, such as audio or video processing. As both are different types of memory, they should be allocated as different carveout. This patch is fixing TCM carveout allocation in lockstep mode.

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.
