> Subject: [PATCH v3 1/1] Makefile: socfpga: Generate sfp file with 4 SPL
> images
>
> Generate 'u-boot-splx4.sfp' which consist of 4 SPL images required for
> booting up Cyclone5/Arria10.
>
> By default, this 'u-boot-splx4.sfp' is generated without extra padding after
> each SPL image.
>
> For Cyclone5, 'u-boot-splx4.sfp' contains:
> 4 x SPL(64KB) = 256KB
>
> For Arria10, 'u-boot-splx4.sfp' contains:
> 4 x SPL(256KB) = 1024KB
>
> For Cyclone5 using NAND flash image layout for 128 KB memory blocks, user
> can 'make' the following target to generate 4 SPL images with
> padding:
>
> make u-boot-spl-padx4.sfp
>
> 'u-boot-spl-padx4.sfp' contains four 128KB SPL images (each 64KB SPL is
> followed by 64KB of zero-padding).
> 4 x (SPL(64KB) + zero-padding(64KB)) = 512KB
