1aa0365f27 sparc32: add init memory poisoning
This patch adds init memory poisoning.  It looks like
totalram_pages was not updated properly in free_initrd_mem
so I fixed that as well.

c4cbe6f96e sparc32: use RTC subsystem
Use rtc subsystem for sparc32 architecture.
Actually, only one driver is needed: m48t59
as it supports the most common clocks on sparc32
machines: m48t08 and m48t02.

[ Add proper RTC layer calls to set_rtc_mmss() -DaveM ]

5280267c1d sparc: Fix handling of LANCE and ESP parent nodes in of_device.c
The device nodes that sit above 'esp' and 'le' on SBUS lack a 'ranges'
property, but we should pass the translation up to the parent node so
that the SBUS level ranges get applied.

Based upon a bug report from Robert Reif.

ba4962d7a6 sparc64: Clean up CPU chip type probing code.
Three main things:

1) Make prober an arch initcall instead of using hard-coded invocation
   from paging_init()

2) Shrink table size, the fpu ident stuff was never used.

3) Use named struct initialized in table.

5110bd21b8 sparc: remove CONFIG_SUN4
While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.

And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.

b69416b51b sparc64: Rewrite central driver.
This driver is now limited to just doing the basic clock board and FHC
chip initialization and registering the platform devices for the
per-board LEDs, which are driven by the new LEDS_STARFIRE driver.

The IRQ register handling is already confined purely to the device
tree code.
