Keystone II load U-Boot from SPI

Hi,

I have a question regarding the booting proces/possibilites of the 66AK2H12.

We are currently developing a custom board with the 66AK2H12 SOC and plan on booting from SPI.
We want to set ARM core0 as boot master, set the boot strap pins to SPI boot, load in a boot configuration table for the DDR3 configuration
and load U-Boot in DDR3 and subsequently run it from DDR3.
After reading the data manual, bootloader user guide and numerous posts on the E2E form it is not very clear if this is possible and if so how it is achieved.

Could someone help me out?

Thanks,

Raymond
