When booting a current kernel with CONFIG_PRINTK_TIME enabled you'll
see messages like:

[    0.000000] time_init: decrementer frequency = 188.044000 MHz
[    0.000000] time_init: processor frequency   = 1504.352000 MHz
[3712914.436297] Console: colour dummy device 80x25

This cause by the initialisation of tb_to_ns_scale in time_init(), suddenly the
multiplication in sched_clock() now does something :).  This patch modifies
sched_clock() to report the offset since the machine booted so the same
printk's now look like:

[    0.000000] time_init: decrementer frequency = 188.044000 MHz
[    0.000000] time_init: processor frequency   = 1504.352000 MHz
[    0.000135] Console: colour dummy device 80x25

Effectivly including the uptime in printk()s.

This patch makes tb_to_ns_scale and tb_to_ns_shift static and
read_mostly for good measure.

Add support to build the PS3 flash rom image and remove some unneeded
lmb calls.

The PS3's lv1 loader supports loading gzipped binary images from flash
rom to addr zero. The loader enters the image at addr 0x100.

In this implementation a bootwrapper overlay is use to arrange for the
kernel to be loaded to addr zero and to have a suitable bootwrapper
entry at 0x100.  To construct the rom image, 0x100 bytes from offset
0x100 in the kernel is copied to the bootwrapper symbol
__system_reset_kernel.  The 0x100 bytes at the bootwrapper symbol
__system_reset_overlay is then copied to offset 0x100.  At runtime the
bootwrapper program copies the 0x100 bytes at __system_reset_kernel to
addr 0x100.

zImage.ps3 is a wrapped image that contains a flat device tree, an lv1
compatible entry point, and an optional initrd.  otheros.bld is the gzip
compresed rom image built from zImage.ps3.  otheros.bld is suitable for
programming into the PS3 boot flash memory.

When the refcount for a device node goes to 0, we call the
destructor - of_node_release(). This should only happen if we've
already detached the node from the device tree.

So add a flag OF_DETACHED which tracks detached-ness, and if we
find ourselves in of_node_release() without it set, issue a
warning and don't free the device_node. To avoid warning
continuously reinitialise the kref to a sane value.

When adding the cputable entry for 440SPe Rev. B, we also need to

they look more bits of the PVR.  The 440SPe Rev. B has PVR 53421891,
which would match the current 440SP Rev. A pattern of 53xxx891.  To
distinguish between 440SP and 440SPe, we need to use the first three
digits of the PVR, which are respectively 532 and 534.

of_device, so only arch/powerpc stuff is capable to use it, which now implies
only mpc885ads reference board.

To cope with the code that should be hooked inside driver, but is really board
specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds
necessary function pointers that are filled in the BSP code.
