Lennert Buytenhek 8b76a68c6c [ARM] 3620/2: ixp23xx: add uengine loader support
Patch from Lennert Buytenhek

This patch allows the ixp2000 uengine loader that is already in the
tree to also be used on the ixp23xx.

Lennert Buytenhek f869afab8f [ARM] 3616/1: fix timer handler wrap logic for a number of platforms
Patch from Lennert Buytenhek

A couple of platforms aren't using the right comparison type in their
timer interrupt handlers (as we're comparing two wrapping timestamps,
we need a bmi/bpl-type comparison, not an unsigned comparison) -- this
patch fixes them up.

Lennert Buytenhek ec8510f6fe [ARM] 3540/1: ixp23xx: deal with gap in interrupt bitmasks
Patch from Lennert Buytenhek

On the ixp23xx, the microengine thread interrupt sources are numbered
56..119, but their mask/status bits are located in bit positions 64..127
in the various registers in the interrupt controller (bit positions
56..63 are unused.)

We don't deal with this, so currently, when asked to enable IRQ 64, we
will enable IRQ 56 instead.

The only interrupts >= 64 are the thread interrupt sources, and there
are no in-tree users of those yet, so this is fortunately not a big
problem, but this needs fixing anyway.

Lennert Buytenhek c471307437 [ARM] 3388/1: ixp23xx: add core ixp23xx support
Patch from Lennert Buytenhek

This patch adds support for the Intel ixp23xx series of CPUs.  The
ixp23xx is an XSC3 based CPU with 512K of L2 cache, a 64bit 66MHz PCI
interface, two DDR RAM interfaces, QDR RAM interfaces, two gigabit
MACs, two 10/100 MACs, expansion bus, four microengines, a Media and
Switch Fabric unit almost identical to the one on the ixp2400, two
xscale (8250ish) UARTs and a bunch of other stuff.

This patch adds the core ixp23xx support code, and support for the
ADI Engineering Roadrunner, Intel IXDP2351, and IP Fabrics Double
Espresso platforms.
