[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 <buytenh@wantstofly.org> Signed-off-by: Deepak Saxena <dsaxena@plexity.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
