nixos: Formally deprecate boot.loader.raspberryPi
The whole option set was recommended against since mid-2019, and never worked with the Raspberry Pi 4 family of devices. We should have deprecated it in early 2020 for removal by 2021. At the time I did not feel confident in making such a decision, and never ended-up getting around to it. The ***only*** supported-by-NixOS boot methods for AArch64 are standards-based boot methods, namely UEFI or the pragmatically almost-standard extlinux-compatible for U-Boot. You can quote me on that.

## Backward Incompatibilities {#sec-release-23.11-incompatibilities}
|
||||
|
||||
- The `boot.loader.raspberryPi` options have been marked deprecated, with intent for removal for NixOS 24.11. They had a limited use-case, and do not work like people expect. They required either very old installs ([before mid-2019](https://github.com/NixOS/nixpkgs/pull/62462)) or customized builds out of scope of the standard and generic AArch64 support. That option set never supported the Raspberry Pi 4 family of devices.
|
||||
|
||||
- `python3.pkgs.sequoia` was removed in favor of `python3.pkgs.pysequoia`. The latter package is based on upstream's dedicated repository for sequoia's Python bindings, where the Python bindings from [gitlab:sequoia-pgp/sequoia](https://gitlab.com/sequoia-pgp/sequoia) were removed long ago.
|
||||
|
||||
- `writeTextFile` now requires `executable` to be boolean, values like `null` or `""` will now fail to evaluate.
