Subject: MPC8272 PCI bridge problem
Date: Fri, 07 Jan 2005 18:03:11 +0300 [thread overview]
Message-ID: <41DEA4AF.8080800@dev.rtsoft.ru> (raw)
Hi to all.
I am working on 8272ADS PCI bridge support in 2.4 kernel.
Does anybody have this working more or less? The point is that it's
nearly works for me, but I can't
get interrupt from CPLD interrupt controller and thus PCI cascade
handler won't triggered even once.
I ioremap IC register (0xf4730000 according to RM) in m8260_setup_arch.
After find_bridges call (where PCI staff is configured in immr) the
values of IC status and mask registers change, though they haven't been
touched in the function.
Any advice or clue will be greatly appreciated.
