[Buildroot] multiple kernel build?

[Buildroot] multiple kernel build?

[Wesley Chow]

I'm having trouble figuring out if buildroot had a mechanism for building
multiple Linux kernels within one image. For example, if I would like to
provide one image for different Raspberry Pi versions or QEMU, I would need
to distribute kernels for different CPU archs (setting aside the problem of
detecting which hardware I'm on in the bootloader). Is this currently
possible?

Thanks,
Wes

If you need to build multiple kernels, then you need one separate
Buildroot configuration for each. Buildroot is very simple: one
Buildroot configuration allows to build one system, i.e one toolchain,
one kernel, one root filesystem image.
