Re: [U-Boot] [PATCH 2/4]: arm: Kirkwood: Fix compiler optimization bug for kwgbe_send

Simon Kagstrom wrote:

kwgbe_send/recv both have loops waiting for the hardware to set a bit. GCC 4.3.3 cleverly optimizes the send case to ... a while(1); loop. This patch uses readl to force a read from device memory. Other volatile accesses have also been replaced with readl/writel where appropriate (as per suggestions on the U-boot mailing list).
