This commit supports booting from stm32 internal nor flash. spl U-Boot initializes the sdram memory, copies next image (e.g. standard U-Boot) to sdram & then jumps to entry point.
Here are the flash memory addresses for U-Boot-spl & standard U-Boot: - spl U-Boot : 0x0800_0000 - standard U-Boot : 0x0800_8000
Is there another patchset missing on mainline for booting via spl?
No, you just need to flash spl & next image at above mentioned addresses. By default spl expects kernel image.
To boot u-boot, press keyboard character 'c'. you might need to keep on pressing 'c' it for some time as the keyboard entry acceptance & detection window is very small.

on mainline with the stm32f746-disco board:
