   4 Subject: [PATCH 11/16] board: sifive: Set LED's color to purple in the U-boot
   5  stage
   6
   7 Set LED's color to purple in the U-boot stage. Because there are still
   8 some functions to be executed before board_early_init_f(), it means
   9 the LED's is not changed to purple instantly when entering the U-boot
  10 stage.
