Hello,
This is v2 of the patchset that adds all the SPL code that is necessary to support the SoCFPGA platform. For v2, here are the changes:
- SDRAM - further clean and addressing all comments. Simplified to only support DDR3, FULLRATE, and Hard PHY. - SDRAM - Moved to drivers/ddr/altera - Move extra code that maps SDRAM to 0x0 in board_init_f
I have pushed a branch to git://git.rocketboards.org/u-boot-socfpga-next.git socfpga_for_next_spl_v2 for testing and reviewing.
Rebased to 2015.04-rc2.
Thanks,
