This patch removes references to the Gateworks Avila Network
Platform in the ixdp425 setup code. Avila setup should occur
separately now that a CF ATA device driver is available.

csum_fold doesn't need two assembly instructions to perform its task,
it can simply add the high and low parts together by rotating by 16
bits, and the carry into the upper-16 bits will automatically happen.
Also, since csum_tcpudp_magic() is just csum_tcpudp_nofold + csum_fold,
use those two functions to achieve this. Also note that there is a
csum_fold() at the end of ip_fast_csum() as well, so use the real
csum_fold() there as well.
Boot tested on Versatile.

This implements the simultaneous read of the isochronous cycle timer and
the system clock (in usecs). This allows to express the exact receive

look more alike and are easier to read. Removed uccf_printk() and related

the type of some variables to their proper type (mostly buffer

During power outages, the UPS notifies the system for a shutdown.
In the current setup, it isn't possible to poweron when power is
restored. This patch fixes the issue by calling the right
ibm,power-off-ups token during such events. It also adds a sysfs
interface so userspace can specify whether or not to power on when
power is restored.

The code for bolting hash entries for ioremap done before proper
mm initialization has a grown a bug when using 64K pages on a
machine where non-cacheable mappings are demoted to 4K HW pages.
The wrong page size index is being passed to the hash table mapping
functions causing a crash at boot on some pSeries machines using
bare metal linux. This fixes it.

The 'linux,boot-cpu' property is obsolete, so remove it from all of the DTS
files and from booting-without-of.txt. The boot CPU is actually defined in
the device tree header, and U-Boot sets that field. The device tree compiler
also complains if the property exists.

scc_uhc.c depends on CONFIG_PCI, not CONFIG_USB. Because CONFIG_PCI
is always "y" on Celleb platform, we move scc_uhc.o to obj-y.

Getting BenH's new EMAC driver working on 440GP, I found some more
problems in the native mode paths of the new DCR code:
- dcr_map() is supposed to return a dcr_host_t, but the native
version is a macro that doesn't expand to an expression. With native
DCRs, dcr_host_t is an empty structure, so we just use a constructor
expression instead.
- dcr_unmap() uses {} instead of the safer do {} while (0)
idiom to implement a no-op
Here's a fix.

This adds driver code for the PMI device found in future IBM products.
PMI stands for "Platform Management Interrupt" and is a way to
communicate with the BMC (Baseboard Management Controller).
It provides bidirectional communication with a low latency.

Add PS3 system manager support and the ppc_md routines restart() and
power_off().
The system manager provides an event notification mechanism for reporting
events like thermal alert and button presses. It also provides support to
control system shutdown and startup.
