Altera Cyclone 5 board is very different board (big, rectangular, expensive) than EBV Socrates (small, circular, cheap) board. Different parts are used there, too, but same configuration of u-boot works on both. Nevertheless, printing wrong name confuses users.
Therefore this splits the configuration so that u-boot knows they are different. So far it is only used for correcting the puts, but there may be other uses in future.

Is there any way at run time to tell which board we are on?
Why do you care about board name in general?
We care for board names for a very long time in U-Boot and I'd like to keep this. I actually expect a sensible board name on any platform that I touch. The board name is an important extra information additional to the SoC name. So the question is the other way round - since when do we _not_ care about board names?
There could be i2c memory on board where you can find out this information but that's problematic if it is empty or you want to use this i2c for something else. For all microblaze boards I use XILINX_BOARD_NAME which reflects hw design (if user is smart enough board name is the part of hw design name). For zynq/socfpga sensible solution is probably to load this name for DTS.
Currently, the SOCFPGA SPL is customized through a set of handoff files which located at board folders. These handoff files are generated by tools based on board and user design in FPGA. With that, not much decision being made during run time based on the board. With this handoff and tools approach, it will shield off the complexity of hardware configuration and errors (if user change it manually without tools help). Thanks
