Subject: [U-Boot-Users] PCI Bridge on 8272ADS
Date: Mon, 04 Apr 2005 22:03:36 +0400	[thread overview]

Hi Wolfgang,
I have a small question - do you have any comments/objection on adding 
support for PCI bridge of 8272ADS to the CVS?
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
