Generate spl/u-boot-splx4.sfp which consist of 4 SPL images required for booting up Cyclone5/Arria10.
For Cyclone5 using NAND flash image layout for 128 KB memory blocks, 'make u-boot-with-nand-spl.sfp' to generate spl/u-boot-nand-splx4.sfp which contains four 128KB SPL images (each 64KB SPL is followed by 64KB of zero-padding).

What changed between V1 and V2 ? Changelog is missing.
In V2, 'make u-boot-with-nand-spl.sfp' will generate spl/u-boot-nand-splx4.sfp which contains 4 x (SPL + 64KB padding). Commit message already mentioned how to generate this SFP file with 64Kb padding for each SPL in SFP.

Also, now that I look at it, if you want to generate some new target, it should be a Makefile target, just like u-boot-with-spl.sfp is a Makefile target. So then you can do make <target>.
There is already a target 'u-boot-with-nand-spl.sfp' in Makefile: u-boot-with-nand-spl.sfp: spl/u-boot-spl.sfp u-boot.img FORCE $(call if_changed,socnandboot)
