The mcu_m4fss_dma_memory_region (0x9cb00000, size 0x100000) overlapped
with uboot_ipc_shm (0x9cbff000, size 0x1000): the IPC window occupies
exactly the last 4 KiB of the DMA region, triggering:
OF: reserved mem: OVERLAP DETECTED!
m4f-dma-memory@9cb00000 overlaps with uboot-ipc-shm@9cbff000
Shrink the DMA region size from 0x100000 to 0xff000, leaving the
last 4 KiB (0x9cbff000–0x9cc00000) exclusively for the U-Boot IPC
sidecar shared-memory window.

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.
