[Qemu-arm] barebox on Canon A1100

[Antony Pavlov]

Hi Sascha!

I have some good news and some bad news.

First the good news.

Barebox was used for Day 18 of QEMU 2018 advent 
(https://www.qemu-advent-calendar.org/2018/).

Here is a quote:

The bad news.

Current master branch barebox for Canon A1100 does not work under qemu,
barebox v2017.02.0 was used for qemu advent.

Thomas Huth reported the problem in the qemu-devel mailing
list two months ago. Please see 
https://www.mail-archive.com/address@hidden/msg571887.html
for details.

The commit a43e2bbc468a71 breaks barebox for Canon A1100:

Any suggestion?
