This patch tries to ensure that phy interrupt pin
won't be asserted after booting. We experienced
following issues with current 88E1121R phy init:
Marvell 88E1121R phy can be hardware-configured
to share MDC/MDIO and interrupt pins for both ports
P0 and P1 (e.g. as configured on socrates board).
Port 0 interrupt pin will be shared by both ports
in such configuration. After booting Linux and
configuring eth0 interface, port 0 phy interrupts
are enabled. After rebooting without proper eth0
interface shutdown port 0 phy interrupts remain
enabled so any change on port 0 (link status, etc.)
cause assertion of the interrupt. Now booting Linux
and configuring eth1 interface will cause permanent
phy interrupt storm as the registered phy 1 interrupt
handler doesn't acknowledge phy 0 interrupts. This
of course should be fixed in Linux driver too.

This patch fixes a problem on systems where the NOR flash is attached
to a 64 bit bus. The toggle bit detection in flash_toggle() is based
on the assumption that the same flash address is read twice without
any other interjacent flash accesses. However, on 32 bit systems the
function flash_read64() [as currently implemented] does not perform
an atomic 64 bit read - instead, this is broken down into two 32 bit
read accesses on addresses "addr" and "addr + 4". So instead of
reading a 64 bit value twice from "addr", we see a sequence of 4 32
bit reads from "addr", "addr + 4", "addr", and "addr + 4". The
consequence is that flash_toggle() fails to work.
This patch implements a simple, but somewhat ugly solution, as it
avoids the use of flash_read64() in this critical place (by breaking
it down manually into 32 bit read operations) instead of rewriting
flash_read64() such to perform atomic 64 bit reads as one could
expect. However, such a rewrite would require the use of floating
point load operations, which becomes pretty complex:
save MSR;
set Floating Point Enable bit in MSR;
use "lfd" instruction to perform atomic 64 bit read;
use "stfd" to store value to temporary variable on stack;
load u64 value from temporary variable;
restore saved MSR;
return u64 value;
The benefit-cost ratio of such an implementation was considered too
bad to actually attempt this, especially as we can expect that such
an implementation would not only have a bigger memory footprint but
also cause a performance degradation.
