* altos: Wait after configuring boot pin before testing itKeith Packard2013-05-07
| | | | | | | | Clearly the pin isn't quite ready just after it's been configured, so hang around for a while (100 nops) to let things setting down before testing the value of the pin. Makes booting a lot more reliable. Signed-off-by: Keith Packard <keithp@keithp.com>
