From: Andrei Gherzan <andrei.gherzan@...>

The new raspberrypi-armv7.conf aims at supporting all the armv7
Raspberry Pi boards.

This initial support was tested on:

- Raspberry Pi 4 Model B
- Raspberry Pi 3 Model B
- Raspberry Pi 0 2 WiFi

Tests:

- Boot
- WiFi
- BT
- Modules load

There is a known limitation of the fact that the core doesn't handle
image depmod for multiple kernels. A set of fixes were proposed for
that:

https://lists.openembedded.org/g/openembedded-core/message/170505
https://lists.openembedded.org/g/openembedded-core/message/170506
https://lists.openembedded.org/g/openembedded-core/message/170507
https://lists.openembedded.org/g/openembedded-core/message/170508

Without these (or similar patches) patches, an additional step is
needed on any board but Raspberry Pi 4: for example running `depmod -a`
at first boot.

Andrei Gherzan (5):
sdcard_image-rpi.bbclass: Move SDIMG_KERNELIMAGE definitions to their
machines
raspberrypi0-2w.conf: Include the RPi 0-2w dtb for all 32-bit machines
rpi-base.inc: Split IMAGE_BOOT_FILES for kernel image
Add support for a multi kernel Raspberry Pi machine
ci: Add raspberrypi-armv7 to the build matrix
