[Buildroot] [PATCH] Enable UART on raspberry pi zero

[Yann E. MORIN]

Luke, All,

On 2017-03-20 12:36 +0000, luke spake thusly:

Then please look at how we're already doing it for the rpi3:

    https://git.buildroot.org/buildroot/tree/configs/raspberrypi3_defconfig

See the following option:

    BR2_ROOTFS_POST_SCRIPT_ARGS="--add-pi3-miniuart-bt-overlay"

Since the thread you pointed to is about rpi3, not rpi0-w, I gues the
workiaround we have will also work for rip0-w.

Can you please check that?

Regards,
Yann E. MORIN.
