Comment:
Here's a template file for `sof-tools`:

```sh
# Template file for 'sof-tools'
pkgname=sof-tools
version=1.9
revision=1
archs="i686* x86_64*"
wrksrc="sof-${version}"
build_wrksrc="tools"
build_style=cmake
hostmakedepends="alsa-utils m4"
makedepends="alsa-lib-devel"
short_desc="Sound Open Firmware and topology binaries - development tools"
maintainer="cinerea0 <cinerea0@protonmail.com>"
license="BSD-3-Clause"
homepage="https://thesofproject.github.io/latest/index.html"
distfiles="https://github.com/thesofproject/sof/archive/refs/tags/v${version}.tar.gz"
checksum=29b83a63720ace3a9173073f12c4dfae5ece841773483cb025623506cd02eccb

post_install() {
	vlicense ../LICENCE
}
```

With this you can get rid of the `sof-tools` subpackage in `sof-firmware`.
