a3613be442 MIPS: Netlogic: Fix frequency calculation register 
Change the PIC frequency calculation to use the register that has the
current configuration. The existing code used the register that is
written to change frequency, which can have an invalid value if the
firmware did not set it up correctly.

edf3ed5e69 MIPS: Netlogic: Update XLP9XX/2XX core freq calculation 
Calculate XLP 9XX and 2XX core frequency from the per-core PLL. This
should give the correct value for all board configurations.

c065909e47 MIPS: Netlogic: PIC freq calculation for XLP 9XX/2XX 
Update PIC frequency calculation for XLP9XX and 2XX processors using
the correct PLL registers. This should work for all possible board
configurations.

861c056953 MIPS: Netlogic: SYS block updates of XLP9XX 
Add the SYS block registers for XLP9XX, most of them have changed.
The wakeup sequence has been updated to set the coherent mode from
the main thread rather than the woken up thread.

57ceb4b020 MIPS: Netlogic: XLP2XX CPU and PIC frequency 
Add code to calculate the CPU and PIC frequency for XLP2XX SoCs.

Since the PIC frequency on XLP2XX can be configured, add a new macro
pic_timer_freq() to be used in netlogic/common/time.c.

7034228792 MIPS: Whitespace cleanup. 
Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

77ae798f5b MIPS: Netlogic: Support for multi-chip configuration 
Upto 4 Netlogic XLP SoCs can be connected over ICI links to form a
coherent multi-node system.  Each SoC has its own set of on-chip
devices including PIC.  To support this, add a per SoC stucture and
use it for the PIC and SYS block addresses instead of using global
variables.

65040e224e MIPS: Netlogic: Add XLP platform files for XLP SoC 
- Update common files to support XLP.
- Add arch/mips/include/asm/netlogic/xlp-hal for register definitions
  and access macros
- Add arch/mips/netlogic/xlp/ for XLP specific files.
