L1TCM is a high performance memory region in MT8192 SCP. Reads L1TCM memory region from DTS to determine if the machine supports. Loads L1TCM memory region to SCP sys if the firmware provides. Starts from MT8192 SCP, the firmware contains physical addresses for each memory region, for instance: Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0xXXXXXX 0xXXXXXXXX 0x10500000 0xXXXXX 0xXXXXX XXX 0xXXXX LOAD 0xXXXXXX 0xXXXXXXXX 0x10700000 0xXXXXX 0xXXXXX XXX 0xXXXX LOAD 0xXXXXXX 0xXXXXXXXX 0x50000000 0xXXXXX 0xXXXXX XXX 0xXXXX Kernel driver can use the "PhysAddr" (i.e. da in the da_to_va callbacks) to know the ELF segment belongs to which region. To backward compatible to MT8183 SCP, separates the da_to_va callbacks for new and legacy version.

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.
