At least Sockit and Socrates are pretty similar in that regard.
Apart from the things that are not ;-)

Take for example the DDR3 pins on the FPGA side.
The Sockit has DDR3-RAM, the Socrates hasn't. So, the pinsetup is different
for both. And when you mess that up in the prebootloader, you can't AFAIK
change that later.
The boards will boot just fine with the same barebox image, but that doesn't
mean, that everything is setup correctly.

I did this for example, because the Socrates needs the i2c clock pulled up.
The Sockit doesn't.
