From a4ca959321da218ebb2e5078831e5ec1f4d8da34 Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Subject: u-boot: rename to uboot

This will allow to match the currently Config.in option
BR2_TARGET_UBOOT, in order to make it easy to integrate U-Boot into
the package infrastructure.
