[Buildroot] [RFC/next v2 1/2] package/rpi-firmware: rework boot/config file handling

[Yann E. MORIN]

Peter, All,

On 2021-03-09 22:29 +0100, Yann E. MORIN spake thusly:
[--SNIP--]
> OK, so here's my new proposal:

I meant:  "not unlike what we do with the busybox default config"

Sorry for any confusion...

Regards,
Yann E. MORIN.

>   - package/rpi-firmware/config.txt is just the common part of all the

> 
>   - change the defconfig files to just set:
>     BR2_PKG_RPI_FW_DTOVERLAY_LIST="miniuart-bt"
> 
> That way, we get best of both worlds:
> 
>   - we avoid duplication of the config.txt, and we can still customise
>     it a bit with just "easy stuff" that we need for our example
>     defconfigs,
> 
>   - users can stil point to their custom, fine-tuned config.txt (in
>     which case they will probably not set BR2_PKG_RPI_FW_DTOVERLAY_LIST)
