When working on this, would it make sense to move the S10 SDRAM driver
to DM, using UCLASS_RAM, like I did for gen5 (see Marek's 'next' branch:
http://git.denx.de/?p=u-boot/u-boot-socfpga.git;a=commit;h=4796a7d5a7fd965c02cf290edec17acb2c9af766)

That might allow us to combine more of the code in mach-socfpga again
in the future...

Regards,
Simon
