	# The anarsoul repo provides rtl8723bs_config.bin, rtl8723cs_xx_fw.bin and rtl8723cs_xx_config.bin
	# linux-firmware in aports provides all three too, but different versions.
	# In particular, linux-firmware's rtl8723cs_xx_fw.bin is extracted from RealTek's Windows driver for the RTL8723BS,
	# and its rtl8723cs_xx_config.bin is symlinked to rtl8723bs_config.bin because the submitter says
	# the BS's _config.bin also works for the CS.
	#
	# However at least on the PinePhone 1.2b (that uses the CS) that last statement is not true.
	# The combination of anarsoul _fw.bin + anarsoul _config.bin works, as well as
	# the combination of linux-firmware _fw.bin + anarsoul _config.bin, but
	# the combination of linux_firmware _fw.bin + linux-firmware _config.bin does not.
	#
	# Until this is resolved, this package provides just the rtl8723cs_xx_config.bin
	# from the anarsoul repo.
	#
	# Note that linux-firmware specifically provides a `rtl8723cs_xx_config.bin.zst`, and the kernel loads
	# `.bin`, `.bin.zst` and `.bin.xz` in that order, so we need to provide either `.bin` or `.bin.zst`
	# to ensure that our firmware gets loaded and not linux-firmware's. The uncompressed file is small enough that
	# zstd'ing it actually increases its file size, so we leave it uncompressed. This also means that
	# we *don't* need to annotate this package with `replaces="linux-firmware"`.
