Hi,
this should be done per-board, so I'd suggest the following: 1) Rename include/configs/socfpga_cyclone5.h to socfpga_cyclone5_socdk.h (to make it in-line with the naming in boards/altera/ , sorry, I forgot about this bit :( You'd also have to fix the MAINTAINERS file to match the adjusted filename). 2) Rename socfpga_arria5.h to socfpga_arria5_socdk.h 3) Enable this for both boards in socfpga_*_socdk.h
Can you do that please ?
Thanks!

btw when doing the rename of the files, use git format-patch -M -C , this will only mark the move in the patch, without doing the removal and insertion of a file, so the diff will be shorter while retaining all the information.

Hi,
this should be done per-board, so I'd suggest the following:
Why? MMC layout is same on all of them...
#define CONFIG_ENV_SIZE 4096
While you are changing that, bigger environment size would be welcome. 32K? Pavel

It doesn't have to be identical. And other boards might want to use e.g. SPI NOR as the environment storage device (I have such a custom board here). So this is definitely a board specific thing.
#define CONFIG_ENV_SIZE 4096

Yes.
Thanks, Stefan
