Bug#891572: better debugging to boot banana pi

[Marc Haber <mh+debian-packages@zugschlus.de>]

Package: flash-kernel
Version: 3.92
Severity: wishlist
Tags: patch

Hi,

the attached modified bootscr.sunxi gives more debugging output and
makes it easier to manually replace a failed boot on the u-boot command
line. Please consider applying it.

Greetings
Marc
