16025ea455 arm: Kirkwood: Check the error summary bit for error detection
The Marvell documentation for the 88f6281 states that the error coding
is only valid if the error summary and last frame bits in the transmit
descriptor status field are set. This patch adds checks for these for
transmit (I would get transmit errors on bootp with the current check,
which I believe are spurious).

7b05f5e027 arm: Kirkwood: Fix compiler optimization bug for kwgbe_send
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).
