Jayachandran C 2a37b1ae44 MIPS: Netlogic: Move from u32 cpumask to cpumask_t
Initial code to support more than 32 cpus. The platform CPU mask
is updated from 32-bit mask to cpumask_t. Convert places that use
cpu_/cpus_ functions to use cpumask_* functions.

Jayachandran C e83fc6be61 MIPS: Netlogic: Move fdt init to plat_mem_setup
At this point early printk is available, so debugging device tree
issues is easier.

Jayachandran C 2f6528e15a MIPS: Netlogic: Add support for built in DTB
Provide a config option to embed a device tree for XLP evaluation
boards. This DTB will be used if the firmware does not pass in a
device tree pointer.

Jayachandran C 1f8a9ef107 MIPS: Netlogic: merge of.c into setup.c
Move the function device_tree_init() from netlogic/xlp/of.c
to setup.c, and remove the wrapper functions reserve_mem_mach()
and free_mem_mach().

Remove file netlogic/xlp/of.c, and the Makefile entry for it.

Ganesan Ramalingam fcf9b4de33 MIPS: Netlogic: Add XLP SoC devices in FDT
Probe and add devices on SoC "simple-bus" on startup. This will
in turn add devices like I2C controller that are specified in the
device tree under 'soc'.

Jayachandran C b876c1a0bc MIPS: Netlogic: Fix TLB size of boot CPU.
Starting other threads in the core will change the number of
TLB entries of a CPU.  Re-calculate current_cpu_data.tlbsize
on the boot cpu after enabling and waking up other threads.

The secondary CPUs do not need this logic because the threads
are enabled on the secondary cores at wakeup and before cpu_probe.

Jayachandran C 66d29985fa MIPS: Netlogic: Merge some of XLR/XLP wakup code
Create a common NMI and reset handler in smpboot.S and use this for
both XLR and XLP.  In the earlier code, the woken up CPUs would
busy wait until released, switch this to wakeup by NMI.

The initial wakeup code or XLR and XLP are differ since they are
started from different bootloaders (XLP from u-boot and XLR from
netlogic bootloader). But in both platforms the woken up CPUs wait
and are released by sending an NMI.

Add support for starting XLR and XLP in 1/2/4 threads per core.

Jayachandran C 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.
