I disagree. I think it's an unnecessary, unneeded, unreasonable tripling of the boot time. Rather than leaving people to patch out this unwanted behaviour, I'd suggest promoting CONFIG_BOOTDELAY into a Kconfig option, leaving the default as-is. This allows the people who want it to configure it easily. In any case the rationale given, that the Riotboard is a dev board used for experimenting, doesn't imply a change like this one. It implies a conversion to use config_distro_bootcmd.h like the patches I've just posted. This also leads to a slightly less unreasonable increase in bootdelay to 2s from config_distro_defaults.h Using config_distro_bootcmd also means that we can largely ignore the u-boot shell altogether and just use extlinux.conf instead _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
