you are correct, I plan to extend current support of devkit3250 board.

I got the point, I will be able to complete board specific changes today
tonight and send them for review.

Please let me ask you for one more advice, if I want to add peripherals
support on the board (by the way thank you for your drivers) and SPL
image building support, both changes touch defconfig and board config
header files. Should I split these changes into separate ones or is one
"board support extension" patch preferred?
