As the default definition breaks booting angler: [ 1.862561] printk: console [ttyMSM0] enabled [ 1.872260] msm_serial: driver initialized D - 15524 - pm_driver_init, Delta cont_splash_mem was introduced in74d6d0a145, but the problem manifested after commit '86588296acbf ("fdt: Properly handle "no-map" field in the memory region")'. Disabling it because Angler's firmware does not report where the memory is allocated (dmesg from downstream kernel): [ 0.000000] cma: Found cont_splash_mem@0, memory base 0x0000000000000000, size 16 MiB, limit 0x0000000000000000 [ 0.000000] cma: CMA: reserved 16 MiB at 0x0000000000000000 for cont_splash_mem Similar issue might be on Google Nexus 5X (lg-bullhead). Other MSM8992/4 are known to report correct address.

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.
