Why should we add a delay for all systems, even when neither U-Boot not Linux will ever use any USB? For example ion boards where not even a USB connector is physically present on the hardware? Please (re-) read the U-Boot Design Principles, item 2 "Keep it fast": http://www.denx.de/wiki/view/U-Boot/DesignPrinciples#2_Keep_it_Fast If USB is not used in U-Boot itself, U-Boot shall not initialize it at all. And we should never impose restrictions or penalties (delays) on everybody for features that are used only by some.

Even if one has to run some risks, one must be brave and strong enough to meet and overcome vexing challenges to maintain a successful business in the long run. I cannot help saying that Americans lack this necessary challenging spirit today. - Hajime Karatsu _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
