From ee50eb8ad3c6405c3685ad7c47ce1a819949834b Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sun, 8 May 2016 15:50:02 +0200 Subject: [PATCH] boards/raspberrypi0: new board Add support for the rpi-0, which is basically a rpi (model A+) in a smaller form-factor. This one does not have an ethernet port, so we just remove it from the configuration (or we could use the existing rasbperrypi_defconfig and suffer from a longer boot time because of the waiting for eth0).
