This reduces the need from two timers to one timer.
Moreover, without this patch, when the "ticker" timer triggers timer_cs_read via
tick_periodic it reads the value of the usual timer it can get an wrapped timer
value without timer_cs_internal_counter having been updated leading to the clock
going backwards. This effectively hangs one cpu that gets stuck in
update_wall_time with an offset slightly smaller than 0xffffffffffffffff.

SPARC/LEON: power down instruction different of different LEONs2011-03-17T01:19:04+00:00Daniel Hellstromdaniel@gaisler.com2011-01-27T01:26:58+00:00urn:sha1:7279b82cb1975ba4e337a549757f17418cfdffad
The way a LEON is powered down is implemented differently depending
on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB
and CHIP.
This is for example needed by the GR-LEON4-ITX board and the UT699.
Previously the power down support for LEON was limited to SMP, now
both SMP and UP systems use the instruction.

SPARC/LEON: added support for IRQAMP IRQ Controller2011-01-04T19:16:36+00:00Daniel Hellstromdaniel@gaisler.com2011-01-04T01:41:30+00:00urn:sha1:e2305e37d4c82ef55be54e9edc8a7e2250739b4f
Needed for LEON AMP systems where different CPUs are routed to
different IRQ controllers. This patch selects the IRQ Controller
which has been routed to the boot CPU, it is up to the boot loader
to configure the IRQ controller.

sparc,leon: CONFIG_SPARC_LEON option and leon specific files.2009-08-18T01:32:09+00:00Konrad Eiselekonrad@gaisler.com2009-08-17T00:13:29+00:00urn:sha1:5213a780295895630530aebacdd19217a5379c9a
The macro CONFIG_SPARC_LEON will shield, if undefined, the sun-sparc
code from LEON specific code. In
particular include/asm/leon.h will get empty through #ifdef and
leon_kernel.c and leon_mm.c will not be compiled.
