It turned out now, that this can solve amount of problems concerning too slow board startup (http://ozlabs.org/pipermail/linuxppc-embedded/2005-March/017447.html) . In short, some PCI cards need the udelay up to (1000000) after deassertion of RST#, which is... slow, at least. While doing all necessary init in the firmware, enough time will almost surely be spent after clearing RST, so that resetting and delay can be eliminated from the kernel code. -- Sincerely, Vitaly
