[Buildroot] [v2 PATCH 0/2] Raspberry-Pi Zero 2 W support

[Buildroot] [v2 PATCH 0/2] Raspberry-Pi Zero 2 W support

[Julien Grossholtz]

Hello,

Here is an update of my previous Raspberry-Pi Zero 2 W support.
As Peter Seiderer pointed out, the Raspberry-Pi Linux Kernel was
updated with a new bcm2710-rpi-zero-2.dtb [1] a few hours after I sent
the patch.

Therefore, I bumped the Raspberry-Pi Linux kernel to 5.10.76 for all related
boards. I built and tested it for the Pis I have access to : Pi Zero W
and Pi 4 (32 and 64 bit versions). But, I cannot test the other.

Regarding the Raspberry-Pi Zero 2 W, I updated the patch with the new
dts and kernel git sha1. I booted it, everything seems to work: HDMI,
Micro SD and Wi-Fi with some extra packages.

Let me know what you think,

Julien Grossholtz

[Buildroot] [PATCH 2/2] board/raspberrypi: add Raspberry Pi Zero 2 W

[Julien Grossholtz]

The Raspberry-Pi Zero 2 W is an affordable single board computer. It is
a more powerful drop-in replacement for the Raspberry Pi Zero W.

The board incorporates an Raspberry-Pi RP3A0 system-in-package (SiP) with
a Broadcom BCM2710A1 and 512MB LPDDR2 SDRAM. The CPU is a quad-core 1Ghz
64-bit Arm Cortex-A53. As for other Raspberry-Pis it also provides
2.4GHz 802.11 b/g/n Wifi, Bluetooth 4.2 and BLE.

The BCM2710 cpu is similar to the Raspberry-Pi 3, it uses the same
kernel configuration as the Raspberry-Pi 3.

Seems you are to fast, with commit [2] a 'bcm2710-rpi-zero-2-w.dtb' was
added (as a permanent replacement/name-change for bcm2710-rpi-zero-2.dtb)

Would like to keep rpi-firmware up-to-date with the rpi-kernel (see
for example [3] and [4])...

Mind to re-spin your patchset?

Peter

Did you see they also updated the supported binaries for the Wi-Fi
firmwares within the dts  [5]  ? I am not sure what it means for the
rpi-wifi-firmware, maybe we will have to bump it at some point too. I will
ensure Wi-Fi is still functional for my board at least.
