Partition currently called "uboot" does not only contain U-boot, but rather it contains TF-A, U-boot and U-boot environment. So, to avoid accidentally deleting the U-boot environment which is located at 0x180000 split the partition. "uboot" is not the correct name as you can't boot these boards with U-boot only, TF-A must be present as well, so rename the "uboot" partition to "firmware". While we are here, describe the NOR node as "spi-flash@0" instead of "m25p80@0" which is the old SPI-NOR driver name. This won't break booting for existing devices as the SoC-s BootROM is not partition aware at all, it will simply try booting from 0x0 of the boot device that is set by bootstrap pins. This will however prevent accidental or automated flashing of just U-boot to the partition.

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.
