Booting gets stuck when systemd is selected in the update-buildroot branch #51

Hi,

Apparently it is not possible to have systemd using the previous buildroot. So I tried the 'update-buildroot' branch to utilize a more up-to-date buildroot. With that, I could change the init system to systemd and included the systemd package in the image. However, the image doesn't boot; after copying the sd card content into the memory and printing the logo on the console, nothing is printed and kernel initialization procedure doesn't start. Since I was able to boot another image generated by the 'update-buildroot' branch, but without systemd, I think the problem probably has to do something with choosing systemd as the init system. Any help to debug this is really appreciated.

Systemd increases bbl.bin's size and the zsbl was copying only the first 16MB of the sd card. I changed bootrom's code to copy 32MB and it got fixed.
