MIPS: Netlogic: Identify XLP 9XX chip

2014-01-24T21:39:48+00:00

Adds processor ID of XLP 9XX to asm/cpu.h.  Update netlogic/xlp-hal/xlp.h
to add cpu_is_xlp9xx() and to update cpu_is_xlpii() to support XLP 9XX.

MIPS: Add support for interAptiv cores

2014-01-22T19:19:01+00:00

The interAptiv is a power-efficient multi-core microprocessor
for use in system-on-chip (SoC) applications. The interAptiv combines
a multi-threading pipeline with a coherence manager to deliver improved
computational throughput and power efficiency. The interAptiv can
contain one to four MIPS32R3 interAptiv cores, system level
coherence manager with L2 cache, optional coherent I/O port,
and optional floating point unit.

MIPS: Add support for the proAptiv cores

2014-01-22T19:18:59+00:00

The proAptiv Multiprocessing System is a power efficient multi-core
microprocessor for use in system-on-chip (SoC) applications.
The proAptiv Multiprocessing System combines a deep pipeline
with multi-issue out of order execution for improved computational
throughput. The proAptiv Multiprocessing System can contain one to
six MIPS32r3 proAptiv cores, system level coherence
manager with L2 cache, optional coherent I/O port, and optional
floating point unit.

MIPS: Netlogic: Add support for XLP2XX

2013-09-03T21:22:19+00:00

XLP2XX is first in the series of 28nm XLPII processors.

The changes are to:
* Add processor ID for XLP2XX to asm/cpu.h and kernel/cpu-probe.c.
* Add a cpu_is_xlpii() function to check for XLPII processors.
* Update xlp_mmu_init() to use config4 to enable extended TLB.
