-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.
-
