Subject: mpc8250 pci registers
Date: Thu, 27 Mar 2003 10:16:15 +0100	[thread overview]
Message-ID: <3E82C15F.7020201@dgt-lab.com.pl> (raw)


anyone has expirience with 8250 PCI interface
i'm trying to read something from pci i/o space, but mpc8250 always
generates 'memory_read' operation on pci bus (i expect io_read to read
registers on my piix device)

here are my pci registers settings:

GPCR=00000000
PCIGCR=01000000 PCIMSK0=c0000000        PCIBR0=80000001
PCIMSK1=c0000000        PCIBR1=80000001 ACR=03
ALRH=30126745
PICMR0=00800fa0 PITAR0=00000000 PIBAR0=00000b00
PICMR1=f0ff0fc0 PITAR1=00000000 PIBAR1=00000800
POCMR0=f0ff0fc0 POTAR0=00000000 POBAR0=00000b00
POCMR1=f0ff0fa0 POTAR1=00000000 POBAR1=00000800

anyone knows what's wrong?
