Subject: [PATCH] arm: cns3xxx: fix writing to wrong PCI registers after
 | 
			
		||||
 alignment
 | 
			
		||||
 | 
			
		||||
Originally, cns3xxx used it's own functions for mapping, reading and writing registers.
 | 
			
		||||
 | 
			
		||||
Commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")
 | 
			
		||||
removed the internal PCI config write function in favor of the generic one:
 | 
			
		||||
 | 
			
		||||
cns3xxx_pci_write_config() --> pci_generic_config_write()
 | 
			
		||||
 | 
			
		||||
cns3xxx_pci_write_config() expected aligned addresses, being produced by cns3xxx_pci_map_bus()
 | 
			
		||||
while the generic one pci_generic_config_write() actually expects the real address
 | 
			
		||||
as both the function and hardware are capable of byte-aligned writes.
 | 
			
		||||
 | 
			
		||||
This currently leads to pci_generic_config_write() writing
 | 
			
		||||
to the wrong registers on some ocasions.
 | 
			
		||||
 | 
			
		||||
First issue seen due to this:
 | 
			
		||||
 | 
			
		||||
- driver ath9k gets loaded
 | 
			
		||||
- The driver wants to write value 0xA8 to register PCI_LATENCY_TIMER, located at 0x0D
 | 
			
		||||
- cns3xxx_pci_map_bus() aligns the address to 0x0C
 | 
			
		||||
- pci_generic_config_write() effectively writes 0xA8 into register 0x0C (CACHE_LINE_SIZE)
 | 
			
		||||
 | 
			
		||||
This seems to cause some slight instability when certain PCI devices are used.
 | 
			
		||||
 | 
			
		||||
Another issue example caused by this this is the PCI bus numbering,
 | 
			
		||||
where the primary bus is higher than the secondary, which is impossible.
 | 
			
		||||
 | 
			
		||||
Before:
 | 
			
		||||
 | 
			
		||||
00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode])
 | 
			
		||||
    Flags: bus master, fast devsel, latency 0, IRQ 255
 | 
			
		||||
    Bus: primary=02, secondary=01, subordinate=ff, sec-latency=0
 | 
			
		||||
 | 
			
		||||
After fix:
 | 
			
		||||
 | 
			
		||||
00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode])
 | 
			
		||||
    Flags: bus master, fast devsel, latency 0, IRQ 255
 | 
			
		||||
    Bus: primary=00, secondary=01, subordinate=02, sec-latency=0
 | 
			
		||||
 | 
			
		||||
And very likely some more ..
 | 
			
		||||
 | 
			
		||||
Fix all by omitting the alignment being done in the mapping function.
 |
