[U-Boot] [PATCH v3 05/19] SPL: FIT: allow loading multiple images

Hi Andre ,

>   ARM Trusted Firmware (ATF))
> - firmware images for management processors (SCP, arisc, ...)
> - firmware images for devices like WiFi controllers
> - bit files for FPGAs
> - additional configuration data
> - kernels and/or ramdisks

Would it be possible to adopt this code to also load SDRAM controller
configuration data?

The issue here is that we need to do it really "early" in SPL, before
SDRAM configuration code (on TI for example).
