drivers/ddr/altera: Add the DDR controller driver for SoCFPGA

From: Dinh Nguyen <[email protected]>

Hello,

The following 2 patches adds the DDR controller driver that is in the Altera SoCFPGA platform. This driver is needed for the SPL on the platform.

Thanks,

2.2.1

From: Dinh Nguyen <[email protected]>

This patch enables the SDRAM controller that is used on Altera's SoCFPGA family. This patch configures the SDRAM controller based on a configuration file that is generated from the Quartus tool, sdram_config.h.

Hi,

current u-boot-socfpga/master doesn't build. Can you please send me a patch(set) for it, so it builds, so I can send it upstream before I start digging in these DRAM patches ?

Thanks!

Best regards,
Marek Vasut

Oops, apologize for that, will rebase and resend.

Thanks,
Dinh

Resend what ? It does not build right now, as it is ...

Best regards,
Marek Vasut
