The Raspberry Pi firmware has assumed that top level #size-cells value in dtb files is 1. As a result, the dts source files have had to use 32-bit sizes, making it awkward to declare memory regions of 4GB or larger, requiring them to be split into chunks. This primarily affects Pi 5, where the dts source has made use of conditional compilation to choose either 64-bit or 32-bit sizes, based on the presence or absence of the defined cpp symbol FIRMWARE_UPDATED. As of EEPROM release pieeprom-2025-02-11, the firmware has read and made use of the actual #size-cells value declared in the dtb, allowing the use of 64-bit sizes. Remove the conditional sections, retaining the 64-bit size values. Signed-off-by: Phil Elwell <phil@raspberrypi.com>
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.
