From e9b72e43d96a1ea2be0f513c78f16743a835d252 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Tue, 1 Nov 2005 19:44:26 +0000 Subject: [ARM] 3064/1: start using ixp2000_reg_wrb Patch from Lennert Buytenhek Switch the users of ixp2000_reg_write that depend on writes being flushed out of the write buffer by the time that function returns over to ixp2000_reg_wrb. When using XCB=101, writes to the same functional unit are still guaranteed to complete in order, so we only need to protect against: - reordering of writes to different functional units - masking an interrupt and then reenabling the IRQ bit in CPSR Signed-off-by: Lennert Buytenhek Signed-off-by: Deepak Saxena Signed-off-by: Russell King --- arch/arm/mach-ixp2000/ixdp2x00.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/arm/mach-ixp2000/ixdp2x00.c') diff --git a/arch/arm/mach-ixp2000/ixdp2x00.c b/arch/arm/mach-ixp2000/ixdp2x00.c index 8b4a839b627..00af934dea3 100644 --- a/arch/arm/mach-ixp2000/ixdp2x00.c +++ b/arch/arm/mach-ixp2000/ixdp2x00.c @@ -81,7 +81,7 @@ static void ixdp2x00_irq_mask(unsigned int irq) dummy = *board_irq_mask; dummy |= IXP2000_BOARD_IRQ_MASK(irq); - ixp2000_reg_write(board_irq_mask, dummy); + ixp2000_reg_wrb(board_irq_mask, dummy); #ifdef CONFIG_ARCH_IXDP2400 if (machine_is_ixdp2400()) @@ -101,7 +101,7 @@ static void ixdp2x00_irq_unmask(unsigned int irq) dummy = *board_irq_mask; dummy &= ~IXP2000_BOARD_IRQ_MASK(irq); - ixp2000_reg_write(board_irq_mask, dummy); + ixp2000_reg_wrb(board_irq_mask, dummy); if (machine_is_ixdp2400()) ixp2000_release_slowport(&old_cfg); -- cgit v1.2.3
