You are right.

I managed to reproduce it:

--- a/board/warp7/warp7.c
+++ b/board/warp7/warp7.c
@@ -71,6 +71,7 @@ int board_init(void)
         /* address of boot parameters */
         gd->bd->bi_boot_params = PHYS_SDRAM + 0x100;

+       printf("******************* 
0123456789012345678901234567890123456789\n");
         return 0;
  }


It does not print correctly:
