 * **sys-firmware/brcm43430-firmware** [upstream](https://github.com/RPi-Distro/firmware-nonfree)
   * Provides a configuration file (`brcmfmac43430-sdio.txt`) that is required for the RPi3/4's integrated WiFi (the main firmware is provided already, by [`sys-kernel/linux-firmware`](http://packages.gentoo.org/package/sys-kernel/linux-firmware)). Now also provides the equivalent file `brcmfmac43455-sdio.txt`, for use with the RPi3 B+ / RPi 4 B's [dual-band WiFi](https://www.raspberrypi.com.tw/tag/bcm2837/) WiFi chip set (Cypress CYW43455), plus the matching `brcmfmac43430-sdio.clm_blob`, and, when the `43455-fix` USE flag is set, also provides a more modern copy of the uploadable file `/lib/firmware/brcm/brcmfmac43455-sdio.bin` (in preference to the older version shipped with `sys-kernel/linux-firmware`; see below).
 
-* **sys-kernel/bcm2711-kernel-bin**
-  * Provides ebuilds to install the available binary packages for the 64-bit `bcm2711_defconfig` Linux kernels (for the Raspberry Pi 4 model B), which are updated weekly [here](https://github.com/GenPi64/bcm2711-kernel).

-* **sys-kernel/bcm2711-kernel-bis-bin**
-
-    Provides ebuilds to install the available binary packages for (slightly tweaked versions of) the 64-bit `bcm2711_defconfig` Linux kernels (for the Raspberry Pi 4 model B), which are updated weekly [here](https://github.com/GenPi64/bcm2711-kernel-bis). This version is used by default in preference to `bcm2711-kernel-bin` as of v1.5.0 of the image, as it includes some additional kernel configuration items such as KVM (but either is acceptable).

-* **sys-kernel/bcmrpi3-kernel-bin**
-  * Provides ebuilds to install the available binary packages for the 64-bit `bcmrpi3_defconfig` Linux kernels (for the Raspberry Pi 3 model B and B+), which are updated weekly [here](https://github.com/GenPi64/bcmrpi3-kernel).

-* **sys-kernel/bcmrpi3-kernel-bis-bin**
-  * Provides ebuilds to install the available binary packages for (slightly tweaked versions of) the 64-bit `bcmrpi3_defconfig` Linux kernels (for the Raspberry Pi 3 model B and B+), which are updated weekly [here](https://github.com/GenPi64/bcmrpi3-kernel-bis). This version is used in preference to `bcmrpi3-kernel-bin` as of v1.2.2 of the bootable image, since it includes some additional kernel configuration items such as KVM (but either is acceptable).

 * **sys-kernel/linux-firmware** [upstream](https://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git)
   * Provides a large collection of redistributable Linux firmware files. The version in this overlay supports the `43455-fix` USE flag, which when set does _not_ install the file `/lib/firmware/brcm/brcmfmac43455-sdio.bin` (allowing a more modern version to be supplied by `sys-firmware/brcm43430-firmware`; see above).
