Thanks you that you're working on this, the dependency is the sunxi sram
controller driver which was supposed to get pulled for 4.1, but like many
other ARM related pull-reqs did not get pulled. And now for 4.2 Arnd
has decided that he does not like the driver even though it was
ok for 4.1, and has not yet answered how else we should solve this...

Arnd, we would really like to move forward with musb support for sunxi
which means we need a solution for the sram controller, can you please
answer Maxime's latest mails on this, or accept the driver as is ?
