board/BuR/brppt1: implement more flexible boot process
With this commit we do: - set the bootdelay in all brppt1 defconfigs to 0, this makes development easier, since we can break into serial console. - move CONFIG_BOOTCOMMAND from header file to defconfig - introduce b_mode variable for selecting the final boot-target. This b_mode represents the boot-switch, which can found on most b&r targets. On the brppt1 this boot-switch is derived from some gpio and the bootcounter within the RTC block, making it so possible to force a boot-target (as example for repair-case). - refactor the environment for booting new flexible way primary we want to get some bootscr.img within the mass-storage, this script then loads everything needed for the boot. For legacy reason we implement the t30lgcy#x boot targets, booting the already delivered linux-images. - make space for the cfgscr within mtdparts on brppt1_nand Signed-off-by: Hannes Schmelzer <oe5hpm@oevsv.at>
