[U-Boot-Users] [PATCH 12/17] Fix fdt_chosen() to call ft_board_setup(), clean up long lines.

Jerry Van Baren gvb.uboot at gmail.com
Thu Jul 5 03:19:53 CEST 2007


The fdt_chosen() function was adding/seting some properties ad-hoc
  improperly and duplicated (poorly) what was done in ft_board_setup()

Clean up long lines (setting properties, printing errors).
