I compiled SPL with your patch and it does boot U-Boot from an SD card. U-Boot functionality seems to be intact too. However, I was unable to install it on the NAND flash. When booting from NAND, SPL does start (the SPL header is displayed), but it fails to load U-Boot with the following errors:
Error: Bad compare! failed
I used similar commands as the ones I use to install X-Loader: CM-T3x # mmc rescan && fatload mmc 0 80a00000 mlo && nandecc hw && nand erase.chip && nand scrub.chip -y && nand write 80a00000 0 30000 CM-T3x # fatload mmc 0 80a00000 u-boot.img && nandecc sw && nand erase 80000 60000 && nand write 80a00000 80000 60000
OK, but why the nandecc switching around? On omap3_beagle _now_ (and for a year or two, but a change from long ago) we do nandecc hw for MLO and U-Boot and get the same 1bit ECC scheme the kernel uses too. I bet the problem is that SPL is loading and expecting the HW scheme, but you wrote in the SW scheme...
