Subject: arm: mvebu: turris_mox: Use show_board_info()
X-Git-Tag: v2022.01~80^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d3159c6b18115cb395ec3c8eb539d9471d2bf862;p=platform%2Fkernel%2Fu-boot.git

arm: mvebu: turris_mox: Use show_board_info()

We are printing board information in last_stage_init(), but U-Boot has
dedicated function, show_board_info(), for this.

Move code which prints board information (board version, serial number,
module topology, ...) to show_board_info().
