Hello,
This patchset adds all the SPL code that is necessary to support the SoCFPGA platform. With this patch series, one should be able to configure the SDRAM controller and run u-boot.
I have pushed a branch to git://git.rocketboards.org/u-boot-socfpga-next.git socfpga_for_next_spl_v1 for testing and reviewing.
Thanks, Dinh
