From b32f40c4853cdbe3d722a959fb0dd1ea048b50d0 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 27 Nov 2007 10:57:27 -0800 Subject: sky2: revert to access PCI config via device space Using the hardware window into PCI config space is more reliable and smaller/faster than using the pci_config routines. It avoids issues with MMCONFIG etc. Reverts: 167f53d05fccb47b6eeadac7f6705b3f2f042d03 Please apply for 2.6.24 Signed-off-by: Stephen Hemminger Signed-off-by: Jeff Garzik --- drivers/net/sky2.h | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) (limited to 'drivers/net/sky2.h') diff --git a/drivers/net/sky2.h b/drivers/net/sky2.h index 69525fd..bc646a4 100644 --- a/drivers/net/sky2.h +++ b/drivers/net/sky2.h @@ -2128,4 +2128,25 @@ static inline void gma_set_addr(struct sky2_hw *hw, unsigned port, unsigned reg, gma_write16(hw, port, reg+4,(u16) addr[2] | ((u16) addr[3] << 8)); gma_write16(hw, port, reg+8,(u16) addr[4] | ((u16) addr[5] << 8)); } + +/* PCI config space access */ +static inline u32 sky2_pci_read32(const struct sky2_hw *hw, unsigned reg) +{ + return sky2_read32(hw, Y2_CFG_SPC + reg); +} + +static inline u16 sky2_pci_read16(const struct sky2_hw *hw, unsigned reg) +{ + return sky2_read16(hw, Y2_CFG_SPC + reg); +} + +static inline void sky2_pci_write32(struct sky2_hw *hw, unsigned reg, u32 val) +{ + sky2_write32(hw, Y2_CFG_SPC + reg, val); +} + +static inline void sky2_pci_write16(struct sky2_hw *hw, unsigned reg, u16 val) +{ + sky2_write16(hw, Y2_CFG_SPC + reg, val); +} #endif -- cgit v1.1
